The invention belongs to the field of a medical technology and specifically relates to a synthetic method of 2-mercaptobenzothiazolyl-(Z)-(2-aminothiazol-4-yl)-2-(tert-butoxycarbonyl) isopropoxyiminoacetate. The synthetic method comprises the following steps: ethyl 2-(2-aminothiazole-4-yl)-2-(1-tert-butoxycarbonyl-1-methylethoxyimino)acetate and 2,2'-dibenzothiazole disulfide are added into a mixed liquor of benzene and acetonitrile; aniline and 2-methylpyridine are successively added; triphenyl phosphite is added dropwise to carry out a reaction; and after the reaction, a crude product is obtained, and the crude product is refined with methanol so as to obtain refined active ester. The synthetic method provided by the invention has simple process and is easy to implement. By the synthetic method, purity of the product reaches more than 99%, and yield reaches more than 94%.
