実験手順

To a solution of 3-bromo-4-fluorobenzylamine hydrochloride (10 g, 42 mmol) and TEA (10.5 g, 103 mmol) in 200 mL of CH2Cl2 was added BOC2O (9.1 g, 42 mmol) at RT. The resulting solution was stirred for 16 h. The solution was diluted with aq. 1 N NaOH and CH2Cl2. The organic layer was washed with brine, dried over Na2SO4, and concentrated to give N-Boc-(3-bromo-4-fluoro-benzyl)amine. MS (ES+): 305 (M+H)+; (ES−): 303 (M−H). Calc'd C12H15BrFNO2-304.16.
