실험 절차

Treat a mixture of (R)-3-[3,5-dichloro-4′-(4-trifluoromethyl-piperidine-1-carbonyl)-biphenyl-4-ylmethyl]-1-(4-triisopropylsilanyloxy-piperidin-1-yl)-pyrrolidin-2-one (0.34 g), THF (6 mL) and water (6 mL) with TFA (2 mL) at room temperature for 1 hour and at 50° C. for 2 hours. Cool the reaction, dilute with ethyl acetate, and wash with sodium bicarbonate (sat.). Dry the organic layer (Na2SO4), remove the solvent in vacuo to afford crude product, and purify on silica gel column with 100% ethyl acetate and 10% methanol in methylene chloride to afford 0.205 g (76%) of the titled product. MS (m/z): 598 (M+).
