Procedure

Acryloyl chloride (0.358 mL, 1M in THF, 0.36 mmol) was added dropwise to a mixture of 4-methoxy-N′-[5-methyl-4-(1-methylindol-3-yl)pyrimidin-2-yl]-6-(4-methylpiperazin-1-yl)benzene-1,3-diamine (Intermediate 77, 164 mg, 0.36 mmol) and DIPEA (0.069 mL, 0.39 mmol) in THF (15 mL) at 0° C. under N2. The resulting suspension was stirred at 0° C. for 1 h, then allowed to warm to r.t. The mixture was then diluted with water (15 mL) and concentrated in vacuo. The resulting material was dissolved in a mixture of CH2Cl2 (20 mL) and CH3OH (5 mL). The resulting solution was washed with water, and sat. brine. The organic solution was then dried (MgSO4) and concentrated in vacuo. Purification by FCC, eluting with 1-8% 7M methanolic ammonia in CH2Cl2 gave a pale yellow dry film after concentration of the appropriate fractions in vacuo. This material was dissolved in CH2Cl2 and the resulting solution was diluted with diethyl ether, which resulted in a beige solid precipitating from the solution. This solid was collected by filtration, washed with diethyl ether and then dried to give the title compound (96 mg, 52%); 1H NMR: 2.26 (3H, s), 2.37 (3H, s), 2.51 (4H, s), 2.87 (4H, s), 3.83 (3H, s), 3.89 (3H, s), 5.70 (1H, d), 6.17 (1H, d), 6.60 (1H, dd), 6.86 (1H, s), 7.09 (1H, t), 7.22 (1H, t), 7.48 (1H, d), 7.87 (1H, s), 8.05 (1H, s), 8.21 (1H, s), 8.37 (1H, d), 8.46 (1H, s), 9.00 (1H, s); m/z: ES+ MH+ 512.46.
