Procedure

Then, 16.2 g (0.1 mol) of 2-amino-5-trifluoromethylpyridine was added to the reaction product, and the mixture was heated to 20° C. and stirred at the same temperature for two hours. The reaction product was analyzed by liquid chromatography, whereby 2-chloroamino-3-chloro-5-trifluoromethylpyridine was found to have decreased to 1%, and 2-chloroamino-5-trifluoromethylpyridine was formed afresh in an amount of 31%, and 2-amino-3-chloro-5-trifluoromethylpyridine was formed in an amount of 30%. The rest was the hydrochloride of 2-amino-3-chloro-5-trimethylpyridine.
