Reaction Steps

A mixture of 4-(2-methoxyphenyl)piperidine (0.2 g, 1.06 mmol), 2-chloromethyl-benzimidazole (186, 1.1 mmol) and Cs2CO3 (0.36 g, 0.36 mmol) in DMF (8 mL) were stirred at room temperature for 18 hours. The reaction mixture was poured into water (30 mL) and extracted with ethyl acetate (20 mL). The organic layer was washed with brine (2×30 mL) and dried over MgSO4, filtered and the filtrate concentrated under reduced pressure. The residue was purified by flash chromatography eluting with 5% methanol in dichloromethane to give the title compound (82 mg, 25%). 1H NMR (CDCl3, 300 MHz) δ 1.69 (m, 4H), 2.19 (m, 2H), 2.87(m, 1H), 2.96 (m, 2H), 3.75 (s, 2H), 3.77 (s, 3H), 6.92 (m, 2H), 7.45 (m, 1H), 7.55 (m, 1H), 12.26 (s, 1H). MS (DCI-NH3) m/z 322 (M+H)+.
