To a solution of {6-[3-(2,6-dichloro-3,5-dimethoxy-phenyl)-1-methyl-3-(2-trimethylsilanyl-ethoxymethyl)-ureido]-pyrimidin-4-yl}-(4-morpholin-4-yl-2-nitro-phenyl)-carbamic acid tert-butyl ester (crude, prepared above) in MeOH (20 mL) was added Raney-Ni (suspension in water) at room temperature, the resulting mixture was stirred for 2 hours under hydrogen atmosphere (1 atm). The reaction was filtered and concentrated. The residue was washed twice with MeOH to obtain title product (160 mg, yield: 70%). MS (ESI): 778 [M+H]+.
