Reaction Steps
To a solution (30 mL) of ethyl 2-chloro-4-fluoro-5-phenyl-1H-pyrrole-3-carboxylate (300 mg) in ethanol was added 10% palladium carbon (50% water-containing product, 0.3 g), and the mixture was stirred under a hydrogen atmosphere at room temperature for 24 hr. The reaction mixture was filtrated, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (eluent: hexane-ethyl acetate=4:1) to give the title compound as a colorless oil (yield 100 mg, 38%).
