Reaction Steps

A mixture of 6-chloro-4-pyrimidinamine (200 mg, 1.544 mmol), Hunig's base (1.2 ml, 6.95 mmol) and (3R)-1,3-dimethylpiperazine (Ref.: WO2009061879 (A1)) (433 mg, 2.316 mmol) in N,N-dimethylformamide (DMF) (2 ml) was heated to 220° C. via a microwave reactor for 15 min. The reaction mixture was purified by RP-HPLC to yield 6-[(2R)-2,4-dimethyl-1-piperazinyl]-4-pyrimidinamine (76 mg, 0.367 mmol, 24% yield). MS (ES+) m/z 208.0 (MH+).
