Procedure

A solution of tert-butyl [3-(2-{2-[(tert-butoxycarbonyl)amino]-5-[(2,5-dichloropyrimidin-4-yl)amino]phenyl}ethyl)phenyl]carbamate (4.70 g, 8.18 mmol) in acetonitrile (750 mL), water (75 mL) and 2-butanol (1.0 mL) was treated with 4.0 M of hydrogen chloride in 1,4-dioxane (7.2 mL, 28.6 mmol) and refluxed for 20 hours. The reaction mixture was concentrated and the tan solid was triturated with dichloromethane and methanol to give the desired product (2.83 g, 84%). LCMS calculated for C18H17ClN5(M+H)+: m/z=338.1. 1H NMR (400 MHz, DMSO-d6): δ 8.37 (s, 1H), 7.89 (s, 1H), 7.79 (s, 1H), 7.59 (m, 1H), 7.43 (m, 3H), 7.36 (d, 1H), 7.17 (m, 2H), 6.91 (dd, 2H), 3.08 (d, 4H).
