87691-88-1, In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles.,87691-88-1 ,3-Piperazinobenzisothiazole hydrochloride, other downstream synthetic routes, hurry up and to see

As a common heterocyclic compound, it belongs to isothiazole compound, name is 3-Piperazinobenzisothiazole hydrochloride, and cas is 87691-88-1, its synthesis route is as follows.

A 2 L reaction flask was charged with 88.5 g (lR, 2R) -1,2-cyclohexanedimethanol dimethanesulfonate, 71.8 g3- (1-piperazinyl) -1,2-benzisothiazole hydrochloride, 77.5 g of potassium carbonate and 1 L of acetonitrile were added and the mixture was heated under reflux with stirring. After the reaction is complete, hotFiltration, filter cake rinse with acetonitrile, the filtrate concentrated to dry under vacuum, in an off-white solid 104. 6g, 88% yield, HPLC purity is greater than99%, m.p. 228-230 C.
