Reaction Steps

Into the reaction flask was added tert-butyl [3-(2-{2-[(tert-butoxycarbonyl)amino]-5-[(2-chloro-5-methylpyrimidin-4-yl)amino]phenyl}ethyl)phenyl]carbamate (0.25 g, 0.45 mmol), methanol (3 mL), and 4.0 M of hydrogen chloride in 1,4-dioxane (5 mL). The reaction mixture was stirred at rt for 16 h and concentrated to give the desired product (0.21 g, 90%). LCMS for C19H21ClN5 (M+H)+: m/z=354.1.
