Reaction Steps

To a mixture of methyl 2-(2,4-dichlorobenzylamino)-4-(trifluoromethyl)pyrimidine-5-carboxylate (443 mg) and ethanol (7 mL) was added a solution of potassium hydroxide (200 mg) in ethanol (4 mL), and the mixture was stirred under heating with reflux for 5 hours. The reaction liquid was concentrated under reduced pressure, water (70 mL) was added to the residue, and the liquid property was made acidic (pH 1) with concentrated hydrochloric acid. The product was extracted with ethyl acetate (200 mL) twice, and then the organic layer was dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure to obtain 2-(2,4-dichlorobenzylamino)-4-(trifluoromethyl)pyrimidine-5-carboxylic acid (411 mg) as a colorless powder.
