Acryloyl chloride (0.026 mL, 1M in THF, 0.32 mmol) was added dropwise to a mixture of N1-(2-dimethylaminoethyl)-5-methoxy-N1-methyl-N4-[5-methyl-4-(1-methylindol-3-yl)pyrimidin-2-yl]benzene-1,2,4-triamine (Intermediate 81, 147 mg, 0.32 mmol) and DIPEA (0.061 mL, 0.35 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, and was then dried (MgSO4) and concentrated in vacuo. Purification by FCC, eluting with 1-8% 7M methnaolic ammonia in CH2Cl2 gave a yellow dry film after concentrating the appropriate fractions in vacuo. This material was dissolved in CH2Cl2 and the resulting solution was diluted with diethyl ether. This was concentrated in vacuo and dried to give the title compound (93 mg, 57%) as a beige solid; 1H NMR: 2.21 (6H, s), 2.28-2.34 (2H, m), 2.37 (3H, s), 2.73 (3H, s), 2.89 (2H, t), 3.81 (3H, s), 3.89 (3H, s), 5.72 (1H, dd), 6.19 (1H, dd), 6.38 (1H, dd), 7.02 (1H, d), 7.06 (1H, d), 7.18-7.23 (1H, m), 7.48 (1H, d), 7.91 (1H, s), 8.06 (1H, s), 8.22 (1H, s), 8.36 (1H, d), 8.75 (1H, s), 10.11 (1H, s); m/z: ES+ MH+ 514.36.
