Procedure

Into a 25 ml, three neck flask under nitrogen atmosphere, a solution of N4-(3-aminophenyl)-5-fluoro-N2-(4-(2-methoxyethoxy)phenyl)pyrimidine-2,4-diamine (0.15 g) in DMF (5 mL) was charged potassium 3-ethoxy-3-oxopropanoate (0.089 g), EDCI.HCl (0.117 g), HOBt (0.093 g) and TEA (0.164 g). The reaction mixture was stirred for 8 hr at room temperature. Completion of the reaction was monitored by TLC using hexane:ethyl acetate (5:5) as the mobile phase. After completion, the reaction mixture was poured into water. The product was extracted with ethyl acetate and the organic layer was washed with brine. The solvent was removed under reduced pressure at 40° C. The obtained solid was purified by triturating with diethyl ether (2×10 mL) to give 0.19 g of ethyl 3-((3-((5-fluoro-2-((4-(2-methoxyethoxy)phenyl)amino)pyrimidin-4-yl)amino)phenyl)amino)-3-oxopropanoate. 1H NMR: DMSO-d6 (400 MHz): 1.182-1.234 (q, 3H, J=6.8), 3.306 (s, 3H), 3.461 (s, 2H), 3.623-3.646 (t, 2H, J=4.8), 4.010-4.033 (t, 2H, J=4.4), 4.090-4.144 (t, 2H, J=7.2), 6.775-6.797 (d, 2H, J=8.8), 7.267-7.283 (d, 2H, J=6.4), 7.511-7.533 (d, 1H, J=8), 7.575-7.591 (d, 1H, J=6.4), 7.817 (s, 1H), 8.058-8.066 (d, 1H, J=3.2), 8.963 (s, 1H), 9.375 (s, 1H), 10.162 (s, 1H).
