Procedure
To a solution of 4,6-dichloropyrimidinamine (2.0 g, 12.2 mmol) in acetonitrile were added Hunig's base (2.34 mL, 13.4 mmol) and dimethylamine (6.7 mL, 13.4 mmol), and the reaction mixture was stirred for 1.5 hours at 50° C. The mixture was poured onto CH2Cl2 and water. The organic layer was separated, washed with brine, and concentrated to afford the title compound (2.2 g, 94%) as an off-white solid. LC-MS (ES) m/z=173, 175 [M+H]+.
