Reaction Steps
To a solution of 4-(3-cyano-4-phenylpyrrole-1-yl)-2-nitro-benzoic acid ethyl ester (0.090 g) in a mixed solvent of methanol (2.5 mL) and ethyl acetate (2.5 mL) was added 10% palladium-carbon powder (0.016 g) under an argon atmosphere, and this mixture was stirred at 40° C. under a hydrogen atmosphere for 3 hours. After this reaction mixture was replaced under an argon atmosphere, the insoluble material was removed by suction through a Celite pad. This filtrate was concentrated under reduced pressure. The residue was purified by column chromatography on aminopropyl silica gel (eluent: ethyl acetate/hexane=50/50) to give the title compound (0.070 g).
