Reaction Steps

Into a reaction flask were added tert-butyl {5-[2-(2-[(tert-butoxycarbonyl)amino]-5-{[(2,5-dichloropyrimidin-4-yl)amino]methyl}phenyl)ethyl]pyridin-3-yl}carbamate (0.44 g, 0.75 mmol), methanol (3 mL), and a solution of hydrogen chloride in 1,4-dioxane (5 mL, 4.0 M). The reaction mixture was stirred at rt overnight and concentrated under vacuum to give the desired product as a white powder (0.40 g, 98%). LCMS for C18H19Cl2N6 (M+H)+: m/z=389.0, 391.0.
