Reaction Steps

A solution of 8.83 g (0.05 mol) of 2,6-difluorobenzoyl chloride in 10 ml of tetrahydrofuran (THF), to which 5.6 g (0.055 mol) of triethylamine had been added, was added dropwise to a solution of 7.65 g (0.05 mol) of 2-trifluoromethyl-2-methylpyrrolidine in 25 ml of tetrahydrofuran (THF). The reaction is exothermic, and slow dropwise addition prevented the temperature from rising above +35° C. Stirring was continued for one hour at room temperature, and the mixture was then poured into 250 ml of ice-water and acidified using dilute hydrochloric acid, and the precipitate obtained was filtered off with suction, washed thoroughly with water and dried. 9.96 g (68% yield of theory) of N-(2,6-difluorobenzoyl)-2-trifluoromethyl-2-methyl-pyrrolidine of melting point 119°-120° C. are obtained.
