Participants

Reaction Steps

N-[2-(6,7-Dihydro-8H-indeno[5,4-d][1,3]oxazol-8-ylidene)ethyl]acetamide (19.0 mg, 0.0784 mmol) was dissolved in methanol (1 mL), a 10% palladium-carbon powder (10 mg) was added, and the mixture was stirred at room temperature for 1 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=90/10) to give the title compound (16.0 mg, yield 84%).
