Paragraph 0033; 0034, (2016/10/10)
The invention discloses a convenient method for preparing aspoxicillin sodium. The method comprises the steps of adding D-aspartic acid into a mixed solution of thionyl chloride and methanol, reacting to prepare D-aspartic acid methyl ester hydrochloride, reacting the D-aspartic acid methyl ester hydrochloride with an aqueous solution of methylamine to obtain aspartic formamide, protecting the first amino on the aspartic formamide by using trifluoroacetyl, then reacting the aspartic formamide with carbonyldimidazole to form an active mixed acid anhydride, condensing the active mixed acid anhydride with an amoxicillin triethylamine salt, finally removing the protective ground and forming a sodium salt under the alkali condition to obtain a crude aspoxicillin product of the target product, and refining the crude product to obtain the high-purity aspoxicillin sodium finished product. The method has the advantages that the reagents are cheap, readily available and low in toxicity and environmental pressure, the process operation is compact and stable, the purity of the product is high and the like.
