Procedure

N-{2-[2-(4-Phenylbutyl)-6,7-dihydro-8H-indeno[5,4-d][1,3]oxazol-8-ylidene]ethyl}propionamide (35.7 mg, 0.0919 mmol) was dissolved in methanol (0.92 mL), a 10% palladium-carbon powder (7 mg) was added, and the mixture was stirred at room temperature for 10 hr under a hydrogen atmosphere. The catalyst was filtered off using celite, and the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography (ethyl acetate/hexane=33/67) to give the title compound (31.2 mg, yield 87%).
