Vorschrift

A mixture of 3.0 g of 2-amino-5-trifluoromethylpyridine and 7 ml of bromoethylacetate was stirred at 80° C. for 1 hour, and concentrated under reduced pressure. The resulting residue was suspended in a mixed solvent of acetonitrile and t-butyl methyl ether, and filtered. The resulting solid was washed with t-butyl methyl ether to obtain 2.46 g of (2-imino-5-trifluoromethyl-2H-pyridin-1-yl)ethyl acetate hydrobromide.
