3-Piperazinobenzisothiazole hydrochloride, cas is 87691-88-1, it is a common heterocyclic compound, the isothiazole compound, its synthesis route is as follows.,87691-88-1
To a solution containing 3- (1-piperazinyl) -1,2_ benzisothiazole hydrochloride (100g) and potassium carbonate (136g) in acetonitrile (800ml) added 1,4_ dibromobutane suspension ( 110g). Vigorous stirring mixture was refluxed for 10 hours, the solvent was distilled off pressure acetonitrile was added water (100ml) and toluene (300ml) to the reaction mixture was distilled net was effected under stirring to break up the product mixture, refluxing under stirring operation , the net after the water addition, cooling down, the suspension was filtered to give a white inorganic salts and organic salts of a mixture of the crude quaternary spiro ammonium base (280g).
With the rapid development of chemical substances, we look forward to future research findings about 3-Piperazinobenzisothiazole hydrochloride
