A solution of acryloyl chloride (1M in CH2Cl2, 0.36 mL, 0.36 mmol) was added dropwise to a solution of 4-[(3S)-3-dimethylaminopyrrolidin-1-yl]-6-methoxy-N-[4-(1-methy-lindol-3-yl)pyrimidin-2-yl]benzene-1,3-diamine (Intermediate 148, 183 mg, 0.40 mmol) in CH2Cl2 (5 mL) at −10° C. over a period of 2 minutes under an atmosphere of N2. The resulting mixture was stirred at 0° C. for 10 minutes and was then allowed to warm to r.t. over 20 minutes. The mixture was then washed with sat. NaHCO3 (2 mL), dried (MgSO4) and concentrated in vacuo. Purification by FCC, eluting with 3-25% CH3OH in CH2Cl2 gave an oil which later crystallised. This solid was triturated and washed with EtOAc (3 mL) to give the title compound (67 mg, 33%) as a pale yellow solid; 1H NMR: 1.77 (1H, m), 2.08 (1H, s), 2.18 (6H, s), 2.72 (1H, m), 3.17 (1H, s), 3.21 (2H, d), 3.32-3.45 (1H, m), 3.87 (3H, s), 3.89 (3H, s), 5.70 (1H, d), 6.22 (1H, d), 6.48-6.58 (1H, m), 6.59 (1H, s), 7.20 (3H, m), 7.51 (1H, d), 7.76 (1H, s), 8.17 (1H, s), 8.28 (1H, d), 8.32 (1H, d), 8.39 (1H, s), 9.33 (1H, s); m/z: ES+ MH+ 512.7.
