Reaction Steps

2-(Bromomethyl)-1-methoxy-4-nitrobenzene (100.0 mg, 0.34 mmol) and tert-butyl 4-(hydroxymethyl)-4-phenylpiperidine-1-carboxylate (93.0 mg, 0.38 mmol) were combined in dimethylformamide (4 mL) and cooled to 0° C. The reaction was treated with sodium hydride (9.0 mg, 0.38 mmol), stirred at 0° C. for 1 hr and at room temperature for 30 min. The reaction mixture was diluted with water and extracted with ethyl acetate (2×). The organic layers were pooled together, washed with brine (2×), dried over sodium sulfate, and concentrated. Column chromatography on silica gel (15% ethyl acetate/hexanes) gave 110 mg (71%). 1H-NMR (CDCl3, 500 MHz) δ 8.11 (dd, J=6.1, 3.1 Hz, 1H), 8.08 (d, J=2.8 Hz, 1H), 7.34 (m, 4H), 7.21-7.24 (m, 1H), 6.80 (d, J=8.9 Hz, 1H), 4.37 (s, 2H), 3.85 (s, 3H), 3.74-3.75 (m, 2H), 3.48 (s, 2H), 3.02-3.07 (m, 2H), 2.21-2.24 (m, 2H), 1.87-1.93 (m, 2H), 1.43 (s, 9H). Mass spec.: 479.16 (MNa)+.
