Reaction Steps

1-{2-(Benzyloxy)-4-[(ethylamino)carbonyl]phenyl}-5-[(benzyloxy)methyl]-N-cyclopropyl-1H-1,2,3-triazole-4-carboxamide (205 mg, 0.390 mmol) obtained in Example 316 was dissolved in methanol (7.0 ml), and the mixture was stirred at room temperature for 4 hr in the presence of 10% palladium carbon (wet, purity 50%, 41 mg) under a hydrogen atmosphere. The reaction mixture was filtrated to remove the catalyst, and the filtrate was concentrated to dryness to give a colorless oil. This was subjected to column chromatography (elution solvent, ethyl acetate-hexane=1:1-4:1) on silica gel (manufactured by E. Merck, Art.7734, 10 g), and the fraction obtained by elution with ethyl acetate-hexane (2:1-4:1) was concentrated and diluted with ethyl acetate-diethyl ether. The precipitate was collected by filtration, washed with diethyl ether and dried to give the title compound as a white powder (131 mg, 0.301 mmol, 77.1%).
