Reaction Steps

Into a mixture of 17.3 g of N-methyl(5-trifluoromethylpyridin-2-yl)-amine and 100 ml of sulfuric acid was dropped 12.3 g of nitric acid, then, the mixture was stirred for 2 hours while heating at 80° C. After cooling down to room temperature, water was poured into the reaction mixture, and the deposited precipitate was filtrated, then, washed with water, then, dried under reduced pressure to obtain 18.8 g of N-methyl(3-nitro-5-trifluoromethylpyridin-2-yl)-amine.
