4-Bromo-isothiazole - Reference Information
| introduction | 4-bromoisothiazole is a pharmaceutical intermediate that can be used in laboratory research and development and chemical synthesis. It can be prepared by one-step bromination of isothiazole and can be used to prepare Bcr-Abl1 kinase inhibitors. |
| Application | 4-bromoisothiazole is a pharmaceutical intermediate, which can be prepared by one-step bromination of isothiazole and can be used to prepare Bcr-Abl1 kinase inhibitors. |
| preparation | add Br2(12.5g,78.12 mmol) dropwise to the solution of isothiazole (5.0g,58.82 mmol) in AcOH(37 mL) at 95 ℃ for 6 h, then cool to RT, and pour into ice water (100mL). The resulting mixture was extracted with Et2O(200mL × 2). The organic phase was washed with 6N NaOH to pH 7~8, dried by anhydrous Na2SO4 and filtered. The filtrate was vacuum concentrated and the resulting residue was purified by distillation to obtain a white solid 4-bromoisothiazole (1.5g,15%). |
