Product Description

The specific preparation process Teriflunomide intermediate of 2-cyano-N-[4-(trifluoromethyl)phenyl]acetamide cas 24522-30-3 was as follows: 205 g of sodium azide, 400 g of 4-trifluoromethylbenzoic acid, 52.4 g of triphenylphosphine, and 28 g of N-chlorosuccinimide were sequentially added to a 3 L round bottom flask. 2.4 L of tetrahydrofuran was stirred and reacted at 15℃ or 5 hours, and the reaction was followed until the reaction of the starting material was completed. After the completion of the reaction, 1.8 L of a solvent was removed under reduced pressure, and then the mixture was poured into 2 L of distilled water, stirred for 30 min, and filtered, and the filter cake was washed with 200 mL of distilled water and 200 mL of ethanol to obtain 388 g of a white solid compound 2-cyano-N-[4-(trifluoromethyl)phenyl]acetamide cas 24522-30-3 which is intermediate of Teriflunomide
