With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.59702-07-7,1-Methylpiperazin-2-one,as a common compound, the synthetic route is as follows.
59702-07-7, To 337 (31.8 mg, 0.0684 mmol) was added l-methylpiperazin-2-one (51.5 mg, 0.342 mmol) and Et3N (50 mu) in DMF (1 mL) and heated at 90 °C for 1 h. Solvent was removed under reduced pressure and the residue was purified by preparatory TLC (CH2Cl2:MeOH, 20: 1) to afford 31.8 mg (86percent) of 344. MS (ESI) m/z [M+H]+ 543.1.
59702-07-7 1-Methylpiperazin-2-one 4399042, apiperazines compound, is more and more widely used in various fields.
