Procedure

N-(2-((6-(3-(2,6-dichloro-3,5-dimethoxyphenyl)-1-methylureido)pyrimidin-4-yl)amino)-5-(piperazin-1-yl)phenyl)acrylamide (Procedure 2L, Example 157) (8.6 g, 0.014 mmol) and DIEA (7.5 μl, 0.043 mmol) were stirred in DCM (1.0 ml) at room temperature under nitrogen atmosphere. A solution of acetyl chloride (1.0 μl, 0.016 mmol) in DCM (11 ul) was added and the reaction mixture was stirred at room temperature for 2 hours. The solvent was evaporated and the resulting material was dissolved in 400 ul of DMSO. The DMSO solution was diluted with 1.0 ml of MeOH and purified by prep-HPLC (water/ACN in formic acid condition) to afford the title compound (1.4 mg, yield: 15%). 1H-NMR (400 MHz, MeOH-d4) δ 2.16 (s, 3H) 3.65-3.80 (m, 4H) 3.94 (s, 6H) 5.76 (dd, 1H) 6.15 (s, 1H) 6.28-6.49 (m, 2H) 6.78-6.82 (m, 1H) 6.95 (dd, 2.89 Hz, 1H) 7.28-7.38 (m, 2H) 8.31 (d, 1H) 8.58 (br. s., 1H); ESI-MS: 643 [M+H]+.
