Reaction Steps

tert-butyl 4-(4-((tert-butoxycarbonyl)(6-(3-(2,6-dichloro-3,5-dimethoxyphenyl)-1-methyl-3-((2-(trimethylsilyl)ethoxy)methyl)ureido)pyrimidin-4-yl)amino)-3-nitrophenyl)piperazine-1-carboxylate (149 g, 0.164 mmol) was stirred in THF (1.5 ml) and MeOH (1.5 ml). Five drops of Raney Nickel suspension in water was added. The solution was stirred under hydrogen atmosphere at room temperature overnight. The reaction was filtered through a pad of Celite®. and filtrate was concentrated to give crude title compound which was taken to the next step without further purification. ESI-MS: 877 [M+H]+.
