실험 절차
To a mixture of 8 g of lysergol in 150 ml of t-butanol, 200 ml of trifluoroacetic anhydride were added dropwise with vigorous stirring. After the solution had been left at room temperature for 90 hours, it was evaporated. The residue was dissolved in water, made alkaline with ammonium hydroxide and the aqueous layer was extracted with ethyl acetate. After removal of the ethyl acetate, the residue was purified by silica gel column chromatography using 1:1 cyclohexane:ethyl acetate for elution to give 6 g of the title compound melting at 181 to 183° C.
