Reaction Steps

In a 25 mL sealable tube under argon were combined 4,6-dichloro-2-pyrimidinamine (0.50 g, 3.05 mmol) and isopropylamine (0.78 mL, 9.15 mmol) in CH3OH (15 mL). The vial was sealed and the resulting mixture was stirred overnight at 50° C. The reaction was cooled to room temperature and stirred over the weekend. The reaction mixture was concentrated, and the resulting orange oil was partitioned between EtOAc and water. The organic layer was separated, washed with brine, dried (MgSO4), filtered and concentrated to afford the title compound (453 mg, 71%) as a yellow foam. LC-MS (ES) m/z=187 [M+H]+.
