It is a common heterocyclic compound, the isothiazole compound, 3-Piperazinobenzisothiazole hydrochloride, cas is 87691-88-1 its synthesis route is as follows.

General procedure: The arylhaloketone (I) (0.1 mol) and the hydrochloride salt of piperazine (pyridinium) compound (II) (0.1 mol) were dissolved in acetonitrile (100 mL) and diisopropylethylamine (0.2 mol) was added.After 12 h at room temperature, TLC (methylene chloride_methanol=20:1) showed that the reaction of starting material (I) was complete.The solvent was concentrated to dryness, and dichloromethane (100 mL) and saturated brine (40 mL) were added and the mixture was stirred for 20 min.The organic layer was dried over anhydrous MgSO4, filtered, concentrated and purified by silica gel column chromatography (eluent:Dichloromethane/methanol = 30:1) gave intermediate (III) in a yield of 60-85% (based on arylhaloketone I).
