Synthesis method of cefoperazone acid

The invention relates to a synthesis method of cefoperazone acid, and belongs to the technical field of medicines. The method comprises the following steps: (1) adopting 7-ACA (7-aminocephalosporanic acid) and 1-methyl-5-mercapto-1,2,3,4-tetrazole as raw materials, allowing reaction between the two raw materials in the catalysis of a boron trifluoride-acetonitrile solution to obtain 7-TMCA (7-amino-3-methyl tetrazolyl cephalosporanic acid) hydrochloride, and performing the protection of carboxyl group and amino group on 7-TMCA hydrochloride with trimethylchlorosilane; (2) allowing reaction of HO-EPCP (2-[(4-ethyl-2,3-dioxopiperazinyl)carbonylamino]-2-(4-hydroxyphenyl)acetic acid) and phosphorus oxychloride in a DMAC (dimethylacetamide) and dichloromethane solution in the protection of nitrogen gas to obtain HO-EPCP chloride; and (3) allowing N-acylation reaction of the 7-TMCA hydrochloride subjected to the protection of carboxyl group and amino group obtained by the step (1) and HO-EPCP chloride obtained by the step (2) with polyethylene glycol 800 as a phase transfer catalyst in a dichloromethane-water mixed solution, regulating pH with a hydrochloric acid solution, and crystallizing to obtain cefoperazone acid. In the invention, the yield of 7-TMCA hydrochloride under the catalysis of boron trifluoride is improved by 3%. The addition of the phase transfer catalyst reduces occurrence of side reaction, improves the reaction yield by 5%, makes the final product yield reach above 69.0%, and improves purity to above 99%.
