実験手順
Add palladium on carbon (720 mg, 10% Pd/C, 50% water by weight) to a nitrogen purged solution of 2-azido-1-(3-(trifluoromethoxy)phenyl)ethanone (1.70 g, 6.93 mmol) in ethanol (15 mL). Purge the flask with hydrogen (balloon). Stir at room temperature overnight. Filter the mixture over Celite®, rinse the Celite® with ethanol (3×30 mL), and concentrate the filtrate in vacuo to provide crude 2-amino-1-(3-(trifluoromethoxy)phenyl)ethanone (1.56 g, 88%). 1H NMR (DMSO-d6) δ 8.56 (br s, 2H), 8.07 (m, 1H), 7.95 (s, 1H), 7.76 (m, 2H), 4.63 (s, 2H).
