Reaction Steps

A 3 N HCl solution in 1,4-dioxane (10 mL) was added to a stirred solution of tert-butyl-2-chloro-4-(3-(5-cyanopyrazin-2-yl)ureido)-5-methoxyphenethyl(4-(4-methylpiperazin-1-yl)benzyl)carbamate (0.5 g) in acetonitrile (50 mL) at 5° C. The reaction mixture was allowed to warm to room temperature and stirring continued for 1 hour. Diethylether (150 ml) was added and the precipitated solid collected by filtration. The solid was triturated with diethylether, methanol, diethylether then dried at reduced pressure to yield the title compound (0.35 g, 70%) as a yellow solid.
