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