Reaction Steps

In a 25 mL sealable tube under argon were combined 4,6-dichloro-2-pyrimidinamine (0.50 g, 3.05 mmol), piperidine (0.75 mL, 7.62 mmol) and CH3OH (10 mL). The vial was sealed and the reaction mixture was stirred for 4 hours at 50° C. The reaction was cooled to room temperature and concentrated. The resulting solid was partitioned between EtOAc and water. The organic layer was separated, dried (MgSO4), filtered and concentrated to afford the title compound (565 mg, 83%) as a yellow solid. LC-MS (ES) m/z=213 [M+H]+.
