Procedure

Acryloyl chloride (0.459 mL, 1M in THF, 0.46 mmol) was added dropwise to a mixture of N-[5-chloro-4-(1-methylindol-3-yl)pyrimidin-2-yl]-4-[(3R)-3-dimethylaminopyrrolidin-1-yl]-6-methoxybenzene-1,3-diamine (Intermediate 85, 226 mg, 0.46 mmol) and DIPEA (0.088 mL, 0.51 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 dried (MgSO4) and concentrated in vacuo. Purification by FCC, eluting with 1-8% 7M methanolic ammonia in CH2Cl2 gave a yellow dry film after concentration of appropriate fractions in vacuo. This material was dissolved in CH2Cl2 and the resulting solution was diluted with diethyl ether. This resulted in a yellow gelatinous solid precipitating from the solution. The mixture was concentrated in vacuo and dried to give the title compound (142 mg, 57%) as a yellow solid; 1H NMR: 1.68-1.81 (1H, m), 2.04-2.14 (1H, m), 2.18 (6H, s), 2.64-2.75 (1H, m), 3.22 (3H, dd), 3.32-3.44 (1H, m), 3.78 (3H, s), 3.90 (3H, s), 5.66 (1H, dd), 6.16 (1H, dd), 6.49 (1H, dd), 6.54 (1H, s), 7.08 (1H, t), 7.23 (1H, t), 7.49 (1H, d), 7.54 (1H, s), 8.29-8.39 (3H, m), 8.53 (1H, s), 9.35 (1H, s); m/z: ES+ MH+ 546.57.
