Reaction Steps

The experiment is carried out as in Example 1, starting with 2-(3-chloropropyl)naphtho[1,8-cd]isothiazole 1,1-dioxide (2.4 g), sodium bicarbonate (0.7 g) and 4-(5-chloro-3-indolyl)-1,2,3,6-tetrahydropyridine (2 g) in dimethylformamide (15 cc) and tetrahydrofuran (15 cc). The mixture is heated for 5 hours at boiling point, then cooled to a temperature of about 20° C. Stirring is maintained for 7 hours at this temperature. After purification by crystallization from water (50 cc), then recrystallization from boiling acetonitrile (50 cc), 2-{3-[4-(5-chloro-3-indolyl)-1,2,3,6-tetrahydro-1-pyridyl]propyl}naphtho[1,8-cd]isothiazole 1,1-dioxide (2.1 g) is obtained, m.p. 189° C.
