Versuchsvorschrift

To a N-methoxy-N-methyl-3-(6-(4-phenoxyphenylamino)pyrimidin-4-ylamino)benzamide (0.150 g, 0.340 mmol) at 0° C. was added 2-methylpropenylmagnesium bromide (6.8 mL, 3.4 mmol, 0.5 M solution in THF). The reaction mixture was allowed to stir at room temperature for min. It was quenched with saturated NH4Cl solution (0.5 mL) and was extracted with EtOAc (2×3 mL). The combined organic layer was washed with brine, dried over Na2SO4, filtered and concentrated under reduced pressure to get a white solid, which was further purified by column chromatography (SiO2, 60-120, product getting eluted in methanol/chloroform:2/98) to give 2-methyl-1-(3-(6-(4-phenoxyphenylamino)pyrimidin-4-ylamino)phenyl)prop-2-en-1-one (I-83) as a white solid. 1H NMR (DMSO-d6) δ ppm: 1.99 (s, 3H), 5.64 (s, 1H), 6.03 (s, 1H), 6.14 (s, 1H), 6.96-7.02 (m, 4H), 7.10 (t, J=7.6 Hz, 1H), 7.25 (d, J=7.6 Hz, 1H), 7.35-7.43 (m, 3H), 7.56 (d, J=8.8 Hz, 2H), 7.88 (d, J=8 Hz, 1H), 7.92 (s, 1H), 8.29 (s, 1H), 9.21 (s, 1H), 9.38 (s, 1H); LCMS: 423 m/e (M+1).
