Reaction Steps

Ethyl 4-(4-((4-(tert-butoxycarbonyl)piperazin-1-yl)methyl)phenylamino)-2-chloro-6-methylpyrimidine-5-carboxylate (0.8 g, 1.63 mmol), K2CO3 (0.56 g, 4 mmol), Pd(PPh3)4 (0.28 g, 0.24 mmol) were dissolved in dioxane/water (20:1), 4-(methoxycarbonyl)phenylboronic acid (0.38 g, 2.1 mmol) was added the mixture was heated to 100° C. for 3 hours. The mixture was diluted with water and extracted with EtOAc. The organic layer was concentrated and purified by column chromatography over silica gel using 30% EtOAc/hexanes as eluent to give the desired product (0.7 g). 1H NMR (400 MHz, DMSO-d6): δ 9.88 (s, 1H), 8.43 (d, J=8.0 Hz, 2H), 8.10 (d, J=8.0 Hz, 2H), 7.68 (d, J=8.4 Hz, 2H), 7.35 (d, J=8.4 Hz, 2H), 4.39 (q, J=6.8 Hz, 2H), 3.89 (s, 3H), 3.49 (s, 2H), 2.68 (m, 4H), 2.50 (s, 3H), 2.33 (m, 4H), 1.91 (t, J=6.8 Hz, 3H), 1.39 (s, 9H); MS m/z 590.2 (M+1).
