The title compound was synthesized following the approach outlined in Procedure 2A (Example 100), modifying step (i) to the following procedure: To a solution of 1-(6-((2-aminophenyl)amino)pyrimidin-4-yl)-3-(2,6-dichloro-3,5-dimethoxyphenyl)-1-methylurea (20 mg, 0.043 mmol), triethylamine (21.8 g, 0.22 mmol), and (Z)-3-chloroacrylic acid (5.5 g, 0.052 mmol) in DCM (0.86 ml, 13.3 mmol), cooled to 0° C. was added 2,4,6-tripropyl-1,3,5,2,4,6-trioxatriphosphinane 2,4,6-trioxide (49 g, 0.78 mmol, 50% solution of EtOAc). The resulting mixture was stirred at room temperature for 2 h and concentrated. The residue was purified by silica gel column chromatography to obtain the title compound (15 mg, yield: 63%). 1H NMR (400 MHz, CDCl3) δ X; MS (ESI): 551.0 [M+H]+.
