87691-88-1, 3-Piperazinobenzisothiazole hydrochloride is a isothiazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
87691-88-1, To a solution containing 3- (1-piperazinyl) -1,2_ benzisothiazole hydrochloride (100g) and potassium carbonate (136g) in acetonitrile(800ml) was added a solution of 1-chloro-4-bromo-butane (88g). 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 (267g).
As the paragraph descriping shows that 87691-88-1 is playing an increasingly important role.
