Sep 2021 News Some tips on 1-Ethylpiperazine-2,3-dione

The synthetic route of 59702-31-7 has been constantly updated, and we look forward to future research findings.

With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.59702-31-7,1-Ethylpiperazine-2,3-dione,as a common compound, the synthetic route is as follows.,59702-31-7

1- (4-bromobutyl) -5-benzyloxy-2- (4-benzyloxy-phenyl) -3-methyl -1H- indole (1.0g, 1.8mmol), 1- ethyl piperazine-2,3-dione (0.5g, 3.6mmol), triethylamine (0.4g, 3.6mmol) placed in 100mL eggplant flask, n-butanol as solvent, the reaction was refluxed for 4h. Rotary evaporation. The residue was mixed with ethyl acetate and dissolved in ethanol, was added 10% Pd / C (0.2g, 0.4mmol), 45 reaction 24h. Filtered off Pd / C, the filtrate by rotary evaporation, column chromatography, as a white oil 0.22g, yield 49.1%

The synthetic route of 59702-31-7 has been constantly updated, and we look forward to future research findings.
