#12. ETH-LAD6-NORLYSERGIC ACID, N,N-DIETHYLAMIDE 6-ETHYL; 6-NORLYSERGAMIDE, N,N-DIETHYL-6-ETHYL; N,N-DIETHYLNORLYSERGAMIDE, 6-ETHYL; N-(6)-ETHYLNORLYSERGIC ACID, N,N-DIETHYLAMIDE; 9,10-DIDEHYDRO-N,N,6-TRIETHYLERGOLINE-8b-CARBOXAMIDE; N-ETHYL-NOR-LSD
|[3D .mol structure]|
To a solution of 0.33 g 6-cyano-nor-LSD in a mixture of 3 mL acetic acid and 0.6 mL H2O, under a nitrogen atmosphere, there was added 0.6 g powdered zinc and the stirred mixture was heated for 4 h with an external oil bath maintained at 130 °C. The reaction mixture was cooled to ice-bath temperature, diluted with an additional 3 mL H2O, and brought to an alkaline pH with the addition of concentrated NH4OH. This suspension was extracted with CH2Cl2 (5x10 mL), the pooled extracts dried with anhydrous Na2SO4, and the solvent removed (after filtration) under vacuum providing a tan solid. Centrifugal chromatography (with alumina and a 9:1 CHCl3/MeOH elution solvent under an ammonia vapor environment), followed by the removal of the solvent under vacuum, yielded a solid product which was recrystallized from EtOAc / hexanes. There was thus obtained 0.19 g (61%) of tan crystals of nor-LSD (9,10-didehydro-N,N-diethylergoline-8b-carboxamide) with a mp of 196-198 °C (dec.).
To a solution of 66 mg nor-LSD in 2 mL freshly distilled DMF under a nitrogen atmosphere, there was added 48 mg anhydrous K2CO3 and 38 mg ethyl iodide. When TLC analysis indicated that the nor-LSD had been consumed (4 h) all volatiles were removed under a hard vacuum. The residue was solubilized in CHCl3 (5x5 mL) and the pooled extracts dried over anhydrous Na2SO4, cleared by filtration, and the solvent removed under vacuum. The residue was separated into two components by centrifugal chromatography (alumina, CH2Cl2, nitrogen and ammonia atmosphere) the first of which was the major product. After removal of the solvent, this was dissolved in hot benzene, filtered and cooled. The addition of hexane prompted crystallization of N-ethyl-nor-LSD (9,10-didehydro-N,N,6-triethylergoline-8b-carboxamide) as a white crystalline product which weighed 66 mg (61%) after drying. It had a mp of 108-110 °C and an [a]D + 40.5 (c 0.46, EtOH).
DOSAGE : 40 to 150 micrograms, orally
DURATION : 8 - 12 hrs
QUALITATIVE COMMENTS : (with 20 µgs, orally) "This has a very real effect at this level, whereas I have no response at all from LSD at 20 mikes."
(with 50 µgs, orally) "This is already coming on in fifteen minutes, and is completely developed in another hour. Very few visual changes or distortions but easy eyes-closed imagery. Pretty much out after ten hours; it was a good, repeatable experiment."
(with 60 µgs, orally) "In about an hour or so, gentle movements of the house plants were noted. The walkway of the painting above the fireplace changed as if the sunny spots were moving ahead. The visual aspects became more LSD-like after a couple more hours, though in a very gentle way. The spider windowpane looked three-dimensional: at first I thought the windows were double-paned, but they were not. Stones, rocks and glass had a magical look to them, but tree bark looked like tree bark. Occasionally, a dark streak (spot) would go through the visual field and a page of a book would move sharply without effort. These aspects were very pleasant to me."
(with 75 µgs, orally) "I am up to a ++ within the hour and am feeling lazy. It is very diuretic and certainly not anorexic. Have been dieting strenuously for the past 4 days, but could definitely be interested in food. Also a decongestant. Body feels balanced. Thinking easy. Concepts easy to follow through. Mind and feelings together as should be. Definitely a plus two, no further. I wonder if it would be possible, at any level, to attain that blurring of boundaries that is the plus three at its best? My mind was at all times capable of realistic and down-to-earth thought, this is not a material that will allow you to float two inches off of the floor."
(with 100 µgs, orally) "It sort of sneaks up on you. Certainly not the push of LSD and, sadly, not the sparkle either. Possible time slowing. Easy sleep and no price to pay the next day."
(with 150 µgs, orally) "Extraordinary experience, none of the demands of LSD, just a completely together trip. There were hints of tummy discomfort and some chills early in the trial, but they were trivial and quickly passed. Fine music, and fine sex."
EXTENSIONS AND COMMENTARY : What a remarkable compound. It is a little more potent than LSD, but much less aggressive in the nature of its action. There appears to be little if any of the push, the taking control nature, of LSD and a greatly modified degree of visual distortion. The warmth and humor appears to be there, but all seems more allowing rather than demanding.
I suspect that this material is rather unstable in solution, even as the tartrate in dilute saline, although I cannot guess why that should be. A few months in the dark, at zero degrees and in the absence of air, led to a very real drop in potency, measured by a control assay of a freshly made solution of the same nominal concentration.
What a difference a single atom makes, an ethyl rather than a methyl group at the ring-D nitrogen atom. The absence of any group there (a hydrogen atom rather than the methyl group of LSD or the ethyl group of ETH-LAD) is nor-LSD, the synthetic intermediate mentioned in the preparation recipe above. It has no activity at all even at a half a milligram. The allyl group at this location gives AL-LAD and the propyl group is PRO-LAD, and both of these are active and have their own individual entries.
