With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.75336-86-6,(R)-2-Methylpiperazine,as a common compound, the synthetic route is as follows.
To a mixture of 6-chloropyridine-3-carbonitrile (10 g, 0.06 mol) and (2R)-2-methylpiperazine(6.35 g, 0.06 mol) in acetonitrile (80 mL), K2C03 (12.0 g, 0.09 mol) was added at RT. Theresulting mixture was stirred at 60°C for 2 h (TLC indicated complete consumption ofstarting material). The reaction was brought toRT, quenched with water (150 mL) andextracted with EtOAc (3 x 80 mL). The combined organic extracts were dried over anhydrousNa2S04 and concentrated under reduced pressure. The residue was purified by columnchromatography (100-200 silica gel, 5percent MeOH-DCM) to afford 6-[(3R)-3-methylpiperazine-1-yl]-pyridine-3-carbonitrile (10.0 g, 69percent yield)., 75336-86-6
The synthetic route of 75336-86-6 has been constantly updated, and we look forward to future research findings.
