実験手順

To a solution (50 mL) of ethyl 2-chloro-5-phenyl-1H-pyrrole-3-carboxylate (8.5 g) in ethanol was added 10% palladium carbon (50% containing water, 0.5 g), and the mixture was stirred under a hydrogen atmosphere at room temperature for 24 hr. The reaction mixture was filtered, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent:hexane-ethyl acetate=9:1→1:1) to give the title compound as a colorless solid (yield 4.50 g, 62%).
