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.
General procedure: To a stirred mixture of homopiperazine (0.60 g, 6.00 mmol), 4-fluorobenzaldehyde (0.60 g, 5.00 mmol) in DCM (15 mL) wasadded AcOH (0.08 mL, 0.50 mmol) and the mixture was stirred atroom temperature for 0.5 h. Then sodium triacetoxyborohydride(1.60 g, 7.50 mmol) was added in portions. The reaction was stirredat the same temperature for 6 h. Finally, the mixture was dilutedwith saturated aqueous NaHCO3 (15.00 mL) followed by water(15.00 mL) and extracted with EtOAc (3 15.00 mL). The organiclayer was dried (MgSO4), filtered, and concentrated in vacuo. Theresidue was purified by column chromatography on silica gel (EtOAc/PE 5:1) to afford yellow oil (0.90 g, yield 77percent)., 75336-86-6
As the paragraph descriping shows that 75336-86-6 is playing an increasingly important role.
