실험 절차

To a solution of 4-(3-cyano-5-benzyloxycarbonylindol-1-yl)benzoic acid ethyl ester (0.16 g) in a mixed solvent of methanol (5 mL) and tetrahydrofuran (5 mL) was added palladium-carbon powder (0.03 g) at 0° C. under an argon atmosphere, and this mixture was stirred at room temperature under a hydrogen atmosphere for 3 hours. The insoluble material was removed by filtration, and the filtrate was concentrated under reduced pressure to give the title compound (0.057 g).
