실험 절차
To a solution of 4-nitro-3-phenyl-isoxazole-5-carboxylic acid ethyl ester (62.3 mg, 0.238 mmol) in EtOH (2.0 mL) is added Raney Ni and the mixture is stirred under hydrogen (balloon) for overnight. The reaction mixture is then filtered through celite and evaporated in vacuo to provide crude 4-amino-3-phenyl-isoxazole-5-carboxylic acid ethyl ester (53.3 mg, 97% yield); HPLC-MS calculated for C12H12N2O3 (M+H+) 233.1. Found: 233.1.
