To a solution of (2-amino-phenyl)-{6-[3-(2,6-dichloro-3,5-dimethoxy-phenyl)-1-methyl-3-(2-trimethylsilanyl-ethoxymethyl)-ureido]-pyrimidin-4-yl}-carbamic acid tert-butyl ester (50 g, 0.075 mmol) and DCC (42 g, 0.2 mmol) in DCM (50 mL) was added a solution of but-2-ynoic acid (13 g, 0.15 mmol) in DCM (10 mL) at 0° C., and the resulting mixture was stirred at room temperature overnight. Water (1 mL) was added to quench the reaction. The mixture was concentrated and the residue was purified by reverse phase chromatography to obtain the title compound (20 mg, yield: 34%). MS (ESI): 659 [M+H]+.
