Procedure

To a solution of ethyl 4-(6-(2,6-dichlorobenzamido)pyrimidin-4-ylamino)benzoate (0.279 g, 0.647 mmol) in THF (5 mL) was added a solution of 3 N LiOH (2 mL). The mixture was heated at 60° C. for 12 hrs. THF was removed under reduced pressure. The residue was diluted with water, acidified with 1 N HCl to pH 3.0. The precipitated white solid was collected by filtration, washed with water, dried in high vacuum to give 4-(6-(2,6-dichlorobenzamido)pyrimidin-4-ylamino)benzoic acid (0.24 g, yield: 92%). 1H NMR (500 MHz, DMSO) δ 12.52 (s, 1H), 11.41 (s, 1H), 10.07 (s, 1H), 8.53 (s, 1H), 7.90 (d, J=8.9 Hz, 2H), 7.85 (d, J=8.9 Hz, 2H), 7.78 (d, J=0.8 Hz, 1H), 7.58-7.53 (m, 2H), 7.49 (dd, J=9.1, 6.9 Hz, 1H). LCMS (ESI) m/z: 403.0 [M+H+].
