Solid NaBH(OAc)3 (1.4 g, 6.8 mmol) was added to a DCE solution (10 mL) of 2-bromo-4-(trifluoromethyl)benzaldehyde (860 mg, 3.4 mmol), 4′-chloro-[1,1′-biphenyl]-4-amine (761 mg, 3.7 mmol), and AcOH (0.78 mL, 13.6 mmol) and the resulting mixture was stirred at room temperature. After 16 h the resulting mixture diluted with EtOAc washed with water and brine, dried (Na2SO4), dry-packed onto silica gel and purified via column chromatography to yield the title compound.
