A mixture of 2-chloro-5-fluoro-N4-(3-methyloxycarbonyl-4-methoxyphenyl)-4-pyrimidineamine (0.15 g, 0.4 mmol), methylamine hydrochloride (0.324 g, 48 mmol) and diisopropylethylamine (0.84 mL, 48 mmol) in MeOH (2 mL) was heated in a sealed tube at 100° C. for 24 h (followed by TLC). The reaction was cooled to room temperature and diluted with H2O (20 mL). The solid was filtered, washed with H2O and dried to obtain 5-fluoro-N4-(3-methylaminocarbonyl-4-methoxyphenyl)-N2-methyl-2,4-pyrimidinediamine R940304. 1H NMR (DMSO-d6): δ 10.65 (1H, s), 8.48 (1H, s), 8.29 (2H, m), 7.93 (1H, m), 7.28 (1H, d, J=9 Hz), 4.00 (3H, s), 2.94 (3H, s), 2.90 (3H, d, J=4.5 Hz); purity: 90%; MS (m/e): 306 (MH+);
