Procedure

To a mixture of 2-chloro-5-trifluoromethylpyridine (18.2) and N-methylpyrrolidone (100 ml), 40% of aqueous methylamine solution (23.3 g) was added, and stirred at room temperature for 3 hours. Water was poured thereinto, and extracted with ethyl acetate 3 times. The combined organic layer was dried over magnesium sulfate, and concentrated under reduced pressure. The residue was subjected to silica gel column chromatography to give 17.3 g of N-methyl-(5-trifluoromethyl-pyridin-2-yl)-amine.
