87691-88-1, 3-Piperazinobenzisothiazole hydrochloride is a isothiazole compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
3. Preparation of ZPR in water/Na3CO . Na2SO4. In a three necked flask was charged BITP HC1 (lOg), CEI (10.35g) Na2C03 (14.1 g, ), Na2SO4 (40g) and water (50. 7g) and the reaction mixture was heated at reflux for 9 hours. After 9 hours reflux, the ziprasidone peak is No.71% area from the reaction mixture.; 6. Preparation of ZPR in the presence of Na2SO4. In a 250g three necked flask was charged water (25ml), Na2C03 (6.91g), Na2S04 (19.72g), BITP HCl (4.9g) and CEI (4.68g). The mixture was stirred at-100C for 12 hours. The isolated solid weights after drying 7.77g (purity by HPLC 85.15%).
The synthetic route of 87691-88-1 has been constantly updated, and we look forward to future research findings.
