SWIM was wondering if anyone knew a link to any possible information regarding lysergic acid sec-butylamide and iso-lysergic acid sec-butylamide or 1-acetyl-LSD and or their respective emetic acitivities, and SWIM knows ALD-52 to be @ 91%. Any experimental data would be useful also. Also any Bees who know a bit about Nick that woould know the way in which he accomlished the epimerization of iso-LSD by dissolving potassium metal in anhydrous ether and then refluxed with anhydrous methanol. After returning to room temperature the iso-LSD was added to the potassium solution and allowed to sit 24 hours at room temperature in the dark, providing a "98.5%" conversion. Swim would be very appreciative for this information.
