Reaction Steps

A mixture of 2-chloro-4-pyrimidinamine (200 mg, 1.544 mmol), Hunig's base (1348 μl, 7.72 mmol) and 4-methyl-4,7-diazaspiro[2.5]octane (Ref.: WO2009061879 (A1)) (338 mg, 1.698 mmol) in N,N-dimethylformamide (DMF) (1.7 ml) was heated to 120° C. via a microwave reactor for 15 min. The reaction mixture was purified by RP-HPLC to yield 2-(4-methyl-4,7-diazaspiro[2.5]oct-7-yl)-4-pyrimidinamine (113 mg, 0.515 mmol, 33% yield). MS (ES+) m/z 220.1 (MH+).
