59702-07-7,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.
EXAMPLE 20 3-chloro-N-(5-chloro-1H-benzimidazol-2-yl-methyl)4-(4-methyl-3-oxo-piperazin-1-yl-carbonyl)-benzamide Prepared analogously to Example 19c from 2-chloro-4-[N-(5-chloro-benzimidazol-2-yl-methyl)-carbamoyl]-benzoic acid, TBTU, diisopropylethylamine and N-methyl-piperazinone in N,N-dimethylformamide. Yield: 8.7percent
The synthetic route of 59702-07-7 has been constantly updated, and we look forward to future research findings.
