실험 절차

To a solution of (6,7-dihydro-8H-indeno[5,4-d][1,3]oxazol-8-ylidene)acetonitrile (210 mg, 1.07 mmol) in ethanol (8 mL) were added Raney cobalt (2 g) and 2N ammonia/ethanol solution (4 mL), and the mixture was stirred at room temperature for 5 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 (NH, ethyl acetate/hexane=50/50→100/0) to give the title compound (60.2 mg, yield 28%).
