Reaction Steps

To a pre-stirred solution of 4-bromo-2-fluorobenzaldehyde (1.82 g, 9.0 mmol) and piperidine (0.97 mL, 9.9 mmol) in DCM (40 mL) at 0° C. was added sodium triacetoxyborohydride (2.85 g, 13.4 mmol) in portions. The reaction mixture was allowed to warm to ambient temperature and stirred for an additional 14 h. The reaction was quenched by the addition of water (30 mL) and extracted with ethyl acetate (75 mL). The organic phase was separated, dried over anhydrous sodium sulfate, filtered and evaporated in vacuo to afford the title compound as a colourless oil (2.6 g, 84%) that was used in the next step without further purification. NMR (CDCl3, 400 MHz): 7.33-7.17 (m, 3H), 3.49 (d, J=1.6 Hz, 2H), 2.43-2.33 (m, 4H), 1.61-1.53 (m, 4H), 1.46-1.38 (m, 2H).
