Procedure

Dissolve 0.40 g (0.9 m mole) of 8-chloro-11-[1-(2-hydroxy-1-phenylethylcarbonyl)-4-piperidylidene]-6,11-dihydro-5H-benzo[5,6]-cyclohepta-[1,2-b]pyridine (Example 41 of Table 2) in 10 mL of pyridine and stir under nitrogen. Add 0.15 g (1.3 m mole) of methanesulfonyl chloride and stir for 20 hours. Concentrate under vacuo and triturate the residue with ether. Purify the resulting solid by silica gel chromatography using 2% MeOH saturated with amonia, and 98% CH2 Cl2 as the solvent. The product is obtained as a white solid, mp=110.7°-111.6° C.
