실험 절차

To a mixture of 5-[4-(4-ethoxycarbonylmethyl-cyclohexyl)-phenyl]-3-methyl-3H-[1,2,3]triazole-4-carboxylic acid benzyl ester (51 mg, 0.11 mmol) and 10% Pd/C (58.8 mg, 0.552 mmol) was added ethyl acetate (5 mL) at room temperature under nitrogen atmosphere. Then, the nitrogen was replaced with a hydrogen gas balloon and the black reaction mixture was stirred for 15 h under hydrogen atmosphere at which time TLC analysis indicated the absence of the starting material. Then, the reaction mixture was filtered and the charcoal was washed with a hot ethyl acetate (50 mL), THF (25 mL), CH3CN (75 mL), and ethanol (25 mL). The filtrate was concentrated under vacuum and the residue was dried under high vacuum to obtain 5-[4-(4-ethoxycarbonylmethyl-cyclohexyl)-phenyl]-3-methyl-3H-[1,2,3]triazole-4-carboxylic acid (40 mg, 97.5% yield) as a white solid. LC/MS calcd. for C20H25N3O4 (m/e) 371, obsd. 372.3 [M+H, ES+].
