실험 절차

To a suspension of S-(−)-2-Hydroxy-1,2,2-triphenylethyl acetate (40.2 g) in 300 mL anhydrous THF at −10 to 0° C. was added a solution of LDA prepared by reaction of diisopropylamine (46.5 mL) with 2.5 M n-BuLi/hexanes (97 mL) in 300 mL anhydrous THF at −5 to 0° C. After stirring at 0° C. for 30 min the mixture was cooled to −78° C. Then, a solution of 5-(4-fluorophenyl)-2-(1-methylethyl)-1-(3-oxopropyl)-N,4-diphenyl-1H-pyrrole-3-carboxamide 1 (50 g) in 280 mL anhydrous THF was added dropwise and maintained at −78° C. for 30 min. After adding 25 mL AcOH and 250 mL water the mixture was allowed to warm to room temperature. The layers were separated and the organic layer was washed and dried. After evaporation of the solvent the crude product was obtained (94 g). Analytical data are consistent with that from the prior art.
