Ammonia → 2-Methyl-4-(trifluoromethoxy)benzamide

Reaction Conditions

Reaction Steps

795 mg (3.61 mmol) of 2-methyl-4-(trifluoromethoxy)benzoic acid are heated under reflux with 4 ml (54.8 mmol) of thionyl chloride and one drop of DMF for 30 minutes. After cooling, the reaction solution is slowly added dropwise into an ice-cooled concentrated aqueous ammonia solution. The resulting precipitate is collected by suction filtration, taken up in 30 ml of water and stirred at 60° C. for 1 h. The mixture is allowed to cool and the solid is collected by filtration and dried in vacuo. Yield: 562 mg (71% of theory).
