실험 절차

To a solution of 5-benzyloxy-2-(3-cyano-4-phenylpyrrole-1-yl)isonicotinic acid ethyl ester in a mixed solvent of methanol (2 mL) and ethyl acetate (2 mL) was added palladium-carbon powder (0.020 g), and this mixture was stirred at room temperature under a hydrogen atmosphere for 30 minutes. The insoluble material was removed by suction through a Celite pad. This filtrate was concentrated under reduced pressure. This obtained solid was washed with diethyl ether, dried to give the title compound (0.040 g).
