Reaction Steps

A mixture of 2-chloro-5-trifluoromethylpyridine (12 g), 70% of aqueous ethylamine solution (16 ml), and NMP (7 ml) was stirred with heating at 70° C. for 1 day. Into the reaction mixture cooled to room temperature, water was poured, and then the precipitated solid was collected by filtration. The obtained solid was washed with water, and dried to give 6.3 g of N-ethyl-(5-trifluoromethylpyridin-2-yl)-amine.
