Procedure
DIPEA (0.3 mL, 1.62 mmol), HATU (0.515 g, 1.355 mmol) and N-methyl piperazine, 6 (0.09 mL, 0.813 mmol) were added to a solution of 4-((tert-butoxycarbonyl)(6-(3-(tert-butoxycarbonyl)-3-(2,6-dichloro-3,5-dimethoxyphenyl)-1-methylureido)pyrimidin-4-yl)amino)-3-nitrobenzoic acid (0.4 g, 0.542 mmol) in DMF (5 mL) at 0° C. under argon atmosphere. The resulting reaction mixture was then allowed to warm to rt and stirred for 18 h. After completion of the reaction by TLC (MeOH:DCM 1:19), water was added to the reaction mixture. The precipitated crude solid was filtered, dried and purified by silica gel column chromatography to obtain the title compound (0.27 g, yield: 61%) as a solid. MS (ESI): 819.1 [M+H]+.
