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.,87691-88-1
2. Preparation of ZPR in glycerol In a three necked flask was charged BITP HC1 (25g, 0. 098 mol), glycerol (62 ml), Na2C03 (13g) and the mixture was stirred for 10 minutes. CEI (5.9g) was added and the reaction mixture was heated for 3h at 115-120C. After 3h, the reaction was almost complete; after cooling to room temperature the solid was filtrated and was triturated in water and dried. The dried solid weights 42 g and the purity was 89.03%.
With the complex challenges of chemical substances, we look forward to future research findings about 87691-88-1,belong isothiazole compound
