Reaction Steps
To a mixture of N-methyl-(5-trifluoromethyl-pyridin-2-yl)-amine (17.3 g) and sulfuric acid (100 ml), nitric acid (12.3 g) was added drop-wise, and stirred with heating at 80° C. for 2 hours. The mixture was cooled to room temperature, and then the reaction mixture was poured into water. The precipitate was collected by filtration, washed with water, and dried under reduced pressure to give 18.8 g of N-methyl-(3-nitro-5-trifluoromethyl-pyridin-2-yl)-amine.
