Temperature: 80 °C

Procedure

To a solution of the 4-(2-chloro-phenyl)-piperidin-4-ol (0.210 g, 1.0 mmol) in isopropanol was added 2,6-lutidine (0.31 mL, 2.7 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 (0.287 g, 0.77 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 (0.200 g, 52%).
