Procedure

4-Bromobenzyl bromide (0.5 g, 2.0 mmol) was stirred with 4-dimethylaminopiperidine (0.51 g, 4.0 mmol) and triethylamine (0.42 mL, 3.0 mmol) in THF (20 mL) at ambient temperature for 96 h. The mixture was diluted with water (50 mL) and extracted with ethyl acetate (50 mL). The organic phase was separated, dried over anhydrous sodium sulfate, filtered and evaporated in vacuo to afford the title compound (0.51 g, 86%). 1H NMR (CDCl3, 400 MHz): 7.44-7.40 (m, 2H), 7.21-7.16 (m, 2H), 3.43 (s, 2H), 2.91-2.85 (m, 2H), 2.27 (s, 6H), 2.17-2.07 (m, 1H), 2.00-1.91 (m, 2H), 1.80-1.72 (m, 2H), 1.58-1.45 (m, 2H).
