실험 절차

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 N-phenylpiperazine (4.8 cc) in toluene (80 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 ethyl acetate as eluant, and recrystallization from boiling acetonitrile (30 cc), 2-[3-(4-phenyl-1-piperazinyl)propyl]naphtho[1,8-cd]isothiazole 1,1-dioxide (5.7 g) is obtained, m.p. 126° C.
