Procedure

To a solution of N4-(6-(methylamino)pyridine-2-yl)-N6-(4-phenoxyphenyl)pyrimidine-4,6-diamine (0.07 g, 0.18 mmol) in NMP (1 mL) was added acryloyl chloride (0.032 g, 0.36 mmol) at 0° C. and the reaction mixture was stirred at rt for 1 h. The reaction mixture was diluted with dichloromethane (2 mL), was washed with NaHCO3 (1 mL), water (1 mL), and brine (1 mL). The dichloromethane solution was dried over Na2SO4 and was concentrated under reduced pressure. The residue was purified by column chromatography (SiO2, 60-120, chloroform/methanol, 9/1) to give N-methyl-N-(6-(6-(4-phenoxyphenylamino)pyrimidin-4-ylamino)pyridin-2-yl)acrylamide (I-78) as a yellow solid. 1H NMR (DMSO-d6) δ ppm: 3.22 (s, 3H), 5.60 (dd, J=2.56 & 9.76 Hz, 1H), 6.12-6.16 (m, 2H), 6.79 (d, J=7.56 Hz, 1H), 6.96 (d, J=8.64 Hz, 5H), 7.09 (t, J=7.32 Hz, 1H), 7.23 (s, 1H), 7.33-7.37 (m, 4H), 7.45 (d, J=8.2 Hz, 2H), 7.32 (t, J=7.8 Hz, 1H), 8.24 (s, 1H); LCMS: m/e 439.3 (M+1).
