A solution of methyl [4,6-bis(dimethylamino)-2-(4-{[4-(trifluoromethyl)benzoyl]amino}-benzyl)pyrimidin-5-yl]acetate (4.34 g, 8.42 mmol) in 20% tetrahydrofuran in methanol (100 mL) was treated with 1N sodium hydroxide solution (25 mL). The resulting mixture was heated at refluxing temperature for 5 hours and then the volatiles were removed by rotary evaporation under vacuum. The remaining aqueous solution was washed with diethyl ether and then neutralized with 1N hydrochloric acid at 0° C. The separated precipitate was collected by suction and rinsed with cold water. Recrystallization from methanol then gave [4,6-bis(dimethylamino)-2-(4-{[4-(trifluoromethyl)benzoyl]amino}benzyl)pyrimidin-5-yl]acetic acid (3.86 g, 81%) as colorless needles.
