Procedure

To a solution of 4-(4-Chloro-phenyl)-3-methyl-piperidin-4-ol (1.0 g, 4.6 mmol) in DMF (10 mL) with triethylamine (1.75 mL, 12.54 mmol), was added 5-(3-Bromo-propylidene)-5,11-dihydro-10-oxa-1-aza-dibenzo[a,d]cyclohepten-7-ol (1.38 g, 4.18 mmol) dropwise for over a period of about 1.5 hours at about 50° C. The reaction was stirred overnight at about 50° C. The reaction was quenched with water, extracted with ethyl acetate, and evaporated in vacuo. The residue was purified by silica gel:chromatography (87:10:3 ethyl acetate:methanol:triethylamine) to yield a brown solid of the title compound.
