Reaction Steps

2-Bromo-5-(trifluoromethyl)benzaldehyde (20 g, 79.1 mmol), ethylamine (2M in MeOH; 59.3 mL, 118.6 mmol), and sodium cyanoborohydride (7.45 g, 118.6 mmol) were combined in MeOH (200 mL). Acetic acid (6.79 mL, 118.6 mmol) was added, and the reaction was stirred at room temperature overnight. The mixture was concentrated and partitioned between CH2Cl2 and H2O. The aqueous layer was separated and extracted twice with CH2Cl2, and the combined organic layers were dried over Na2SO4 and concentrated to give (2-bromo-5-trifluoromethyl-benzyl)-ethyl-amine.
