With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.109384-27-2,1-Methylpiperazin-2-one hydrochloride,as a common compound, the synthetic route is as follows.
A mixture of Example 18B (0.179 g, 1.0 mmol), l-methylpiperazin-2-one, hydrochloric acid (0.301 g, 2 mmol), and triethylamine (0.405 g. 4.0 mmol) in ethanol (10 mL) was heated under reflux for 16 hours. The solvent was removed, and the residue was purified by flash column chromatography on silica gel eluting with 1-5 % methanol in ethyl acetate to afford 0.21 g (82%) of the title compound.
109384-27-2, 109384-27-2 1-Methylpiperazin-2-one hydrochloride 17060766, apiperazines compound, is more and more widely used in various fields.
