摘 要:以氮甲基哌嗪为原料,经对硝基苯甲酰氯酰化和硝基Fe粉还原两步反应合成了医药中间体4-[(4-甲基-1-哌嗪基)羰基]苯胺,并通过单因素实验优化合成工艺。酰化反应:溶剂为CH2Cl2,缚酸剂为K2CO3,收率95.67%。还原反应用NH4Cl活化后的Fe粉为还原剂,投料比为n(4-[(4-甲基-1-哌嗪基)羰基]硝基苯)∶n(铁粉)∶n(NH4Cl)=1∶4∶4,收率90.14%。总收率82.97%。

Abstract:4-[(4-Methyl-1-piperazinyl)carbonyl] aniline was synthesized through a two-step reaction including acylation and reductionby one-factor experiment to determine the most excellent synthesis process using nitrogen-methyl piperazine as the raw material. The results showed that: in acylation reaction, N-methyl piperazine and p-nitrobenzoyl chloride were reacted to prepare 4-[(4-methyl-1-piperazinyl) carbonyl] nitrobenzenethe;a yield of 95.67% was achieved using CH2Cl2 as the solvent and K2CO3 as the deacid reagent.While in thereduction reaction,the reduction4-[(4-Methyl-1-piperazinyl)carbonyl]nitrobenzene by Fe was actived by NH4Cl to preparation 4-[(4-methyl-1-piperazinyl) carbonyl] aniline;a yield of 90.14% was achieved when.the ratio of 4-[(4-methyl-1-piperazinyl) carbonyl] nitrobenzene: iron: NH4Cl was 1∶4∶4. A total yield of 82.97% was achieved.
Key words:4-[(4-methyl-1-piperazinyl) carbonyl] aniline; medicine intermediate; one-factor experiment
