Reaction Steps

To a solution of methyl 2-(2,4-dichlorophenylamino)-4-trifluoromethyl-pyrimidine-5-carboxylate (0.358 g) in ethanol (8 ml) was added a solution of potassium hydroxide (190 mg) in ethanol (8 ml) and the solution stirred at reflux for 24 h. Ethanol was removed under reduced pressure and water (15 ml) added. The solution was washed with ether and concentrated hydrochloric acid was added to adjust the acidity to pH 1. The precipitated solid was filtered, washed with water and dried in vacuo at 50° C. to afford 2-(2,4-dichlorophenylamino)-4-trifluoromethyl-pyrimidine-5-carboxylic acid (262 mg).
