Procedure

N-[2-(2-Methyl-6,7-dihydro-8H-indeno[5,4-d][1,3]oxazol-8-ylidene)ethyl]acetamide (165 mg, 0.644 mmol) was dissolved in methanol (6.4 mL), a 10% palladium-carbon powder (82 mg) was added, and the mixture was stirred at room temperature for 12 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/methanol=100/0→95/5) to give the title compound (148 mg, yield 89%).
