Problems solved by technology

But quaternary ammonium salts such as tetrabutyl ammonium acetate and sulfonic acid binding effect are poor, feed equivalent is higher, raw material price is more expensive, and the purity of this sulfonic acid quaternary ammonium salt intermediate is not high, and this not only increases production cost, and is harmful to Subsequent product quality has a certain impact
At the same time, this route uses high-boiling n-butyl acetate washing reaction system and toxic crystallization solvent 4-methyl-2-pentanone, which is not easy to remove residual solvent, and the operation is cumbersome, which affects the product quality of subsequent avibactam sodium
Therefore, this route is not conducive to industrial scale-up production

Abstract

The invention discloses an avibactam intermediate compound, disulfonic acid gemini quaternary ammonium salt, and a preparation method thereof, and relates to medical compounds and organic chemical synthesis, and the preparation method of the avibactam intermediate compound disulfonic acid gemini quaternary ammonium salt comprises the following steps: (1) carrying out hydrogenolysis sulfonation reaction on (2S,5R)-6-hydroxy-7-oxo-1,6-diazabicyclo[3.2.1]octane-2-formamide; (2) after the reaction in the previous step is completed, performing suction filtration, washing filtrate once, and adding gemini quaternary ammonium salt for reaction; and (3) after the reaction in the previous step is completed, carrying out extraction, rotary evaporation and crystallization. Compared with the prior art,the method has the advantages that the operation is simple, the raw materials are easy to obtain, the cost is lower, the dosage of the gemini quaternary ammonium salt is lower, the purity of the obtained disulfonic acid gemini quaternary ammonium salt is higher, and the HPLC relative purity of avibactam sodium generated by sodium salt exchange of the disulfonic acid gemini quaternary ammonium salt is greater than 99.5%, so that the process is suitable for large-scale production.

Description

technical field [0001] The invention relates to the field of pharmaceutical compounds and organic chemical synthesis, in particular to an avibactam intermediate compound and a preparation method thereof. Background technique [0002] Avibactam sodium, chemical name: [(1R,2S,5R)-2-(aminocarbonyl)-7-oxo-1,6-diazabicyclo[3.2.1]oct-6-yl]sulfuric acid - Sodium salt, belonging to diazabicyclooctone compound, it is a new type of β-lactamase inhibitor, which can effectively inhibit class A, class C and part of class D β-lactamase. In 2015, the compound preparation of avibactam and ceftazidime was approved by the US FDA for the treatment of severe infections caused by drug-resistant bacteria, and its effect is significantly higher than that of clavulanic acid, sulbactam and tazobactam that have been marketed . Therefore, avibactam has broad application prospects, but the difficulty of avibactam synthesis hinders its industrial production and wider application. [0003] At present,...
