Sulfuric Acid → 2,4,5-Trifluorobenzamide

Participants

Reaction Steps

In 20 ml of 80% sulfuric acid was dissolved 5.8 g of 2,4,5-trifluorobenzonitrile and the mixture was heated under reflux for 30 minutes. After cooling, the reaction mixture was poured into ice-water and extracted with ethyl acetate. The extract was dried over sodium sulfate and the solvent was removed to yield 5.32 g of 2,4,5-trifluorobenzamide.
