A mixture of the 1-(2-nitrophenyl)cycloheptene (1.00 g, 4.61 mmol) produced in Example (44a), 10% palladium on carbon (300 mg, wet) and methanol (130 mL) was stirred for 21 hours at atmospheric pressure and room temperature under a hydrogen atmosphere. The reaction mixture was filtered and the filtrate was concentrated under reduced pressure. The obtained residue was purified by silica gel column chromatography (ethyl acetate/heptane) to give 539 mg of the title compound as a light orange oil.
