Procedure

To a solution of the product of Step 1 (252 mg, 1.18 mmol) in isopropyl alcohol (5 mL) was added 2,6-lutidine (197 mg, 214 uL, 1.84 mmol) and potassium iodide (few mg). The resulting suspension was warmed to 80° C. Solid 2-[5-(3-Bromo-propylidene)-5,11-dihydro-10-oxa-1-aza-dibenzo[a,d]cyclohepten-7-yl]-propan-2-ol (221 mg, 0.591 mmol) was added in approximately equal portions over 2 h. Stirring was continued an additional 20 h at 80° C. The mixture was concentrated and the resulting residue purified by silica gel chromatography (methylene chloride to methylene/methanol 95:5 gradient) to afford the title compound (160 mg, 54%).
