Reaction Steps
The experiment is carried out as in Example 1, starting with 2-(3-chloropropyl)naphtho[1,8-cd]isothiazole 1,1-dioxide (7 g), triethylamine (3.5 cc) and 4-(2-fluorophenyl)piperazine (4.4 g) in toluene (150 cc). The mixture is heated for 8 hours at boiling point, then cooled to a temperature of about 20° C. After purification by flash-chromatography on a silica column, under a current of argon at medium pressure (0.5-1.5 bar) with dichloromethane as eluant, and recrystallization from boiling acetonitrile (15 cc), 2-{3-[4-(2-fluorophenyl)-1-piperazinyl]propyl)naphtho[1,8-cd]isothiazole 1,1dioxide (4.8 g) is obtained, m.p. 112° C.
