実験手順

To a stirred solution of N2-(6-(4-phenoxyphenoxy)pyrimidin-4-yl)pyridine-2,6-diamine (0.65 g, 1.75 mmol) in NMP (10 mL) was added dimethylaminocrotonyl chloride (1.026 g, 7 mmol) at 0° C. The reaction mixture was allowed to come to room temperature and kept at it for 1 h. It was diluted with dichloromethane (10 mL), was washed with NaHCO3 solution (2 mL) and water (2 mL), and dried over Na2SO4. The dichloromethane solution was filtered and was concentrated under reduced pressure to give a residue that was purified by column chromatography (SiO2, 60-120, chloroform/methanol, 9/1) to give (E)-4-dimethylamino)-N-(6-(6-(4-phenoxyphenoxy)pyrimidin-4-ylamino)pyridin-2-yl)but-2-enamide (I-82) as an off white solid. 1H NMR (DMSO-d6) δ ppm: 2.19 (s, 6H), 3.08 (d, J=5.52 Hz, 2H), 6.50 (d, J=15.4 Hz, 1H), 6.77 (td, J=5.92 & 15.4 Hz, 1H), 7.00-7.07 (m, 5H), 7.15 (t, J=7.36 Hz, 1H), 7.21 (dd, J=2.2 & 8.92 Hz, 2H), 7.41 (t, J=7.52 Hz, 2H), 7.68 (t, J=7.96 Hz, 1H), 7.77 (d, J=7.96 Hz, 1H), 7.95 (s, 1H), 8.35 (s, 1H), 10.20 (s, 1H), 10.40 (s, 1H); LCMS: m/e 483 (M+1).
