Reaction Steps
The experiment is carried out as in Example 1, starting with 2-(3-chloropropyl)naphtho[1,8-cd]isothiazole 1,1-dioxide (8.5 g), triethylamine (4.2 cc) and 4-(4-chlorophenyl)-1,2,3,6-tetrahydropyridine (5.7 g) in toluene (80 cc). The mixture is heated for 8 hours at boiling point, then cooled to a temperature of about 20° C. Stirring is continued for 8 hours at this temperature. After purification by flash-chromatography on a silica column, under a current of argon at medium pressure (0.5-1.5 bar) with ethyl acetate as eluant, and recrystallization from boiling acetonitrile (50 cc), 2-{3-[4-(4-chlorophenyl)-1,2,3,6-tetrahydro-l-pyridyl]propyl}naphtho[1,8-cd]isothiazole 1,1-dioxide (4.9 g) is obtained, m.p. 111° C.
