To a solution of 1-(2-amino-5-bromo-phenyl)-ethanone (2.4 g, 11.2 mmol) in anhydrous methanol (50 mL) was added sodium borohydride (1 g, 26 mmol) at rt under nitrogen. The mixture was stirred for 1 h, poured onto ice water, and extracted with ethyl acetate (3×30 mL). The combined organic layers were dried (MgSO4) and concentrated to yield the title compound as an off-white solid (2.1 g, 86%): mp 95-96° C.
