With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1152367-80-0,(S)-1,3-Dimethylpiperazine,as a common compound, the synthetic route is as follows.
Part A 2-[(2S)-2,4-Dimethyl-1-piperazinyl]-4-pyrimidinamine A mixture of 2-chloro-4-pyrimidinamine (200 mg, 1.544 mmol), Hunig’s base (1348 mul, 7.72 mmol) and (3S)-1,3-dimethylpiperazine (Ref.: WO2009061879 (A1)) (318 mg, 1.698 mmol) in N,N-dimethylformamide (DMF) (1.7 ml) was heated to 220 C. via a microwave reactor for 15 min. The reaction mixture was purified by RP-HPLC to yield 2-[(2S)-2,4-dimethyl-1-piperazinyl]-4-pyrimidinamine (88 mg, 0.425 mmol, 28% yield). MS (ES+) m/z 208.0 (MH+).
1152367-80-0, 1152367-80-0 (S)-1,3-Dimethylpiperazine 13152036, apiperazines compound, is more and more widely used in various fields.
