Participants

Reaction Steps

To a solution of 4-(5-Bromo-pyridin-2-yloxy)-benzaldehyde (RH3-A02640-038) (3.501 g, 12.6 mmol) in 1,2-dichloroethane (61 mL) is added isoamylamine (1.65 mL, 14.2 mmol), NaBH(OAc)3 (4.00 g, 18.9 mmol), and acetic acid (1.10 mL, 19.2 mmol). The reaction is stirred overnight. The reaction mixture is then washed with saturated NaHCO3 (2×100 mL), dried over MgSO4, filtered, and concentrated. The mixture is loaded on silica gel, eluted with hexanes with a gradient from 25% of ethyl acetate to 100% of ethyl acetate to give [4-(5-Bromo-pyridin-2-yloxy)-benzyl]-(3-methyl-butyl)-amine (2.18 g, 50%) as a yellow oil. 1NMR (400 MHz, CDCl3) δ ppm: 8.21 (d, J=3.1 Hz, 1H), 7.75 (dd, J=2.6, 8.7 Hz, 1H), 7.37-7.34 (m, 2H), 7.09-7.05 (m, 2H), 6.82 (d, J=9.1 Hz, 1H), 2.49 (s, 2H), 2.66 (dd, J=7.6, 7.6 Hz, 2H), 1.67-1.61 (m, 1H), 1.44-1.38 (m, 2H), 1.15 (s br, 1H), 0.90 (d, J=6.6 Hz, 6H); MS (ES): [M+H]+ found 261.7.
