With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.109-01-3,1-Methylpiperazine,as a common compound, the synthetic route is as follows.
To a mixture of 4-FLUORO- benzonitrile 42B (1.0 g, 8. 25 MMOL) and K2CO3 (2.27 mg, 16.51 MMOL) in dimethyl sulfoxide (7 mL) was added 1-methyl piperazine (1.36 mL, 12. 38 MMOL) and the reaction continued as described above to afford amine 1.54 g of 45b in 93% YIELDS. 1H-NMR (500 MHz, CDC . S) : No. 2.36 (3Hs, s), 2.55 (4Hs, t, J = 4. 88 Hz), 3.35 (4Hs, t, J = 4. 88 Hz), 6. 87 (2Hs, d, J = 8. 78 Hz), 7.49 (2Hs, d, J = 8. 78 Hz); ESI-MASS : 202. 1 (M+1)., 109-01-3
109-01-3 1-Methylpiperazine 53167, apiperazines compound, is more and more widely used in various fields.
