A solution of acryloyl chloride (0.035 mL, 0.44 mmol) in CH2Cl2 (1 mL) was added to a mixture of 2-{[5-amino-4-(2-dimethylaminoethyl-methylamino)-2-methoxyphenyl]-amino}-4-(1-methylindol-3-yl)pyrimidine-5-carbonitrile (Intermediate 102, 171 mg, 0.36 mmol) and DIPEA (0.120 mL, 0.73 mmol) in CH2Cl2 (3 mL) at 0° C., then the mixture was stirred at 0° C. for 1 h. The mixture was then diluted with CH2Cl2, washed twice with sat. NaHCO3, and then water, then dried (MgSO4) and concentrated in vacuo. Purification by FCC, eluting with 0-5% methanolic ammonia in CH2Cl2 gave the title compound (68 mg, 36%) as a yellow solid; 1H NMR: (100° C.) 2.22 (6H, s), 2.40 (2H, t), 2.76 (3H, s), 2.98 (2H, t), 3.77 (3H, s), 3.90 (3H, s), 5.69 (1H, dd), 6.17 (1H, dd), 6.40 (1H, dd), 7.02-7.06 (2H, m), 7.21-7.25 (1H, m), 7.49 (1H, d), 8.23 (1H, d), 8.45 (1H, s), 8.47 (1H, s), 8.63 (1H, s), 8.86 (1H, s), 9.59 (1H, s); m/z: ES+ MH+ 525.32.
