To the solution of 4,6-dichloro-2-(methylthio)-5-pyrimidinecarbonitrile (2.20 g, 10.0 mmol) in DMF (10 mL) was added 2,6-difluoroaniline (2.17 mL, 20.0 mmol). The solution was stirred at 50° C. for about 60 minutes. The mixture was slowly added into a solution of MeOH (20 mL) and water (30 mL). The resultant solid was filtered and washed with MeOH/H2O (20 mL, 1:1) to give 4-chloro-6-[(2,6-difluorophenyl)amino]-2-(methylthio)-5-pyrimidinecarbonitrile as a white solid (2.82 g, 90%). LC-MS m/z 313 (M+H)+; 1H-NMR (CDCl3) δ 2.33 (s, 3H), 6.94 (s, 1H), 7.04 (m, 2H), 7.35 (m, 1H).
