Reaction Steps

Heat in an oil bath at 170° C. a mixture of 15 g. of 5-bromo-2-chloro-nicotinic acid, 12.2 g. of 2-methyl-3-trifluoromethyl aniline and 60 g. of phenol for three hours. Treat the resulting reaction mixture with ether and 5% sodium bicarbonate solution, concentrate and steam distil to obtain an oily residue. Dissolve the oily residue in dilute sodium hydroxide solution, acidify with dilute hydrochloric acid and filter. Recrystallize the product from methanol to yield 5-bromo-2-(2-methyl-3-trifluoromethylanilino) nicotinic acid, m.p. 222°-224° C.
