Reaction Steps

40% Dimethylamine in water (1466 μl, 11.58 mmol) was added into the mixture of 2-chloro-4-pyrimidinamine (300 mg, 2.316 mmol) in N,N-dimethylformamide (DMF) (1.5 ml). The resulting reaction mixture was heated in a microwave reactor at 220° C. for 30 min. The reaction mixture was purified by RP-HPLC to yield N,N-dimethyl-2,4-pyrimidinediamine (290 mg, 2.099 mmol, 91% yield) as a white solid. MS (ES+) m/z 139.2 (MH+).
