Reaction Steps
5 ml of 35% concentrated hydrochloric acid (10 ml, 57 mmol) was added to 4-trifluoromethylnicotinamide (90 g, 10 mmol), and the mixture was heated under reflux for 5 hours. Water (50 ml) was added, and the mixture was adjusted to pH 3 using sodium carbonate, and then extracted with ethyl acetate twice. The organic layers were combined, dried over magnesium sulfate and then concentrated under reduced pressure to obtain 1.71 g (yield 89.7%) of the title compound.
