Procedure

To a solution of the 4-(4-chloro-2-methyl-phenyl)-piperidin-4-ol (0.160 g, 0.71 mmol) in isopropanol was added 2,6-lutidine (0.24 mL, 2.1 mmol) and catalytic potassium iodide. This mixture was heated to 80° C., and treated with 2-[5-(3-Bromo-propylidene)-5,11-dihydro-10-oxa-1-aza-dibenzo[a,d]cyclohepten-7-yl]-propan-2-ol (0.221 g, 0.59 mmol), added in portions over 1 h. The solution was then stirred at 80° C. for an additional 14 h. The reaction was concentrated in vacuo, then purified by Isco flash chromatography (15% methanol/85% methylene chloride) to yield the title compound (0.130 g, 36%). 1H-NMR (CDCl3): δ 1.57 (s, 6H), 1.92 (d, 2H), 2.30 (t, 2H), 2.49 (s, 3H), 2.48–2.63 (m, 2H), 2.74–3.11 (m, 6H), 3.40 (s, 1H), 5.21 (bs, 2H), 6.09 (t, 1H), 6.75 (d, 1H), 7.06 (d, 1H), 7.08 (s, 1H), 7.20(d, 2H), 7.22–7.36 (m, 1H), 7.57 (d, 1H), 8.36 (dd, 1H). ESI-MS m/z: 519 (M+1), retention time 1.61.
