Ethylamine → 6-Chloro-n4-ethylpyrimidine-2,4-diamine

Participants

Reaction Steps

In a 50 mL flask under argon were combined 4,6-dichloro-2-pyrimidinamine (0.50 g, 3.05 mmol) and ethylamine (2.0 M in CH3OH) (15.24 mL, 30.5 mmol) and the reaction mixture was stirred at 50° C. for 3 hours. The mixture was cooled to room temperature and concentrated. The resulting yellow solid was dissolved in EtOAc and the solution was washed with water. The organic layer was dried (MgSO4), filtered and concentrated to afford the title compound (368 mg, 69%) as a yellow solid. LC-MS (ES) m/z=173 [M+H]+.
