With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.109-07-9,2-Methylpiperazine,as a common compound, the synthetic route is as follows.
A. To a solution of 2-methylpiperazine (0.10 g, 1 mmol) in CH2Cl2 (2 mL) was added 4-fluorobenzyl bromide (0.125 mL, 1 mmol). The resultant mixture was stirred at ambient temperature. After 15 hours, the mixture was concentrated in vacuo to afford a solid. This solid was dissolved in CH2Cl2 and washed sequentially with water, aqueous NaHCO3 solution, then brine. The organic layer was dried over MgSO4, filtered, and concentrated to an oil. Purification by flash column chromatography afforded 0.025 g (12% yield) of 1-(4-fluorobenzyl)-3-methylpiperazine, a compound of formula (C), as a colorless oil; NMR (CDCl3) 7.3 (m, 2), 7.0 (m, 2), 3.4 (s,2), 3.0-2.6 (m, 5), 2.0 (br s, 2), 1.6 (t, 1), 1.0 (d, 3) ppm.
109-07-9, The synthetic route of 109-07-9 has been constantly updated, and we look forward to future research findings.
