Reaction Steps

A solution of acryloyl chloride (0.522 mL, 1M in CH2Cl2, 0.52 mmol) was added dropwise to 4-(3-dimethylaminoazetidin-1-yl)-N-[4-(1H-indol-3-yl)pyrimidin-2-yl]-6-methoxy-benzene-1,3-diamine (Intermediate 166, 224 mg, 0.52 mmol) in CH2Cl2 (10 mL) and the mixture was then stirred at −5° C. for 1 h. The mixture was then diluted with CH2Cl2 (100 mL), and the resulting solution was washed with sat. NaHCO3 (25 mL), water (25 mL), and then sat. brine (25 mL) and then concentrated in vacuo. Purification by FCC, eluting with 0-30% CH3OH in CH2Cl2 gave the title compound (46 mg, 18%) as a beige solid; 1H NMR: 2.09 (6H, d), 3.09 (1H, s), 3.56 (2H, t), 3.85 (3H, s), 3.96 (2H, t), 5.68 (1H, dd), 6.20 (1H, dd), 6.26 (1H, s), 6.50 (1H, dd), 7.14 (2H, dt), 7.18 (1H, t), 7.40-7.46 (1H, m), 7.82 (1H, s), 7.90 (1H, s), 8.23 (1H, d), 8.31 (1H, d), 8.38 (1H, d), 9.34 (1H, s), 11.76 (1H, s); m/z: ES+ MH+ 484.
