Name is 3-Piperazinobenzisothiazole hydrochloride, as a common heterocyclic compound, it belongs to isothiazole compound, and cas is 87691-88-1, its synthesis route is as follows.,87691-88-1
Excess dried, -325 mesh potassium carbonate (257 mg, 1.86 MMOL) was diluted in 4 mL acetonitrile and 3-piperazin-1-yl-benzoisothiazole hydrochloride (395 mg, 1.55 MMOL), catalytic potassium iodide, and 1 (2- chloroethoxy)-4-nitrobenzene (250 mg, 1.20 MMOL) were added. This mixture was sealed in a Smith microwave vial and heated on the Smith Workstation at 150 C for 1.5 h. After cooling, the salts were filtered off and washed with ACETONITRILE and the filtrate was concentrated. The residue was taken up in methylene chloride and washed with water. The organic layer was dried over sodium sulfate, and concentrated to afford 530 mg of a yellow solid. Yield 89%; 92% HPLC purity at 214 nm; mp 115 C ; MS (APCI) : 385 [M+H] +.
With the complex challenges of chemical substances, we look forward to future research findings about 3-Piperazinobenzisothiazole hydrochloride
