Procedure

Dissolve 0.3 g (0.56 m mole) of 8-chloro-11-[1-(2-methanesulfonyloxy-1-phenylethylcarbonyl)-4-piperidylidene]-6,11-dihydro-5H-benzo-[5,6]cyclohepta-[1,2-b]pyridine (Formula 5.6 of Example 83) in 5 mL of DMF and add 0.2 g (0.6 m mole) of cesium thioacetate (preparation described in Synthetic Communications, 13, 553, 1983). Stir the reaction at 80° C. for twenty hours then concentrate under vacuo. Purify the residue by silica gel chromatography using 70% EtOAc and 30% hexane as the solvent. The product is obtained as a light brown solid, mp=92.7°-93° C.
