|  |  | 3-(2-Chlorophenyl)-5-methylisoxazole-4-carbonyl chloride Usage And Synthesis | 
 | Chemical Properties | 3-(2-Chlorophenyl)-5-methylisoxazole-4-carbonyl chloride is Cream solid |  | Uses | 3-(2-Chlorophenyl)-5-methylisoxazole-4-carbonyl chloride is used for preparing isoxazolyl penicillin derivatives. |  | Flammability and Explosibility | Notclassified |  | Synthesis | To the solution was dropwise added under cooling at -12° to -14°C a solution of 3-(2-chlorophenyl)-5-methylisoxazol-4-carbonyl chloride, which was prepared from 3-(2-chlorophenyl)-5-methylisoxazol-4-carboxylic acid (1.78 g.) and thionyl chloride (10 ml.), in methylene chloride and then stirred for 5 hours. After the reaction, to the solution was added ice-water, and the resulant mixture was washed with water, dilute phosphoric acid, an aqueous solution of sodium bicarbonate and water in turn, and dried over magnesium sulfate. |
