Reaction Steps

To a solution of a nearly 1:1 mixture (3.41 g) of methyl 2-chloro-5-(4-cyclohexylphenyl)-1H-pyrrole-3-carboxylate and methyl 2-amino-5-(4-cyclohexylphenyl)-3-furoate in methanol (30 mL) and ethyl acetate (10 mL) was added 10% palladium carbon (50% containing water, 0.34 g), and the mixture was stirred under a hydrogen atmosphere at 50° C. for 14 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=3:1→2:1) to give the title compound as crystals (yield 1.25 g, 41%).
