실험 절차
10% Pd/C (0.60 gm, 0.56 mmol) was added to a solution of 5-(3-Nitrophenyl)oxazole (5.80 gm, 30.50 mmol) in MeOH (122 mL). A H2 atmosphere was then introduced via balloon. After 24 h the reaction mixture was filtered through Celite. The catalyst was rinsed with MeOH and the filtrate was concentrated to give the product 3-(oxazol-5-yl)aniline (4.82 gm, 30.10 mmol, 99% yield) as a white solid. Anal. Calcd. for C9H6N2O3 m/z 160.1, found: 161.1 (M+H)+. Crude product was used without purification.
