Macrocyclic lactone impurity synthetic method
-
Paragraph 0030; 0031, (2017/04/28)
The invention relates to a method for preparing an azithromycin impurity I and an azithromycin impurity E. The method comprises the following steps: mixing azithromycin with a solvent, and adding the mixture into a compound which is shown as (I) in the description to perform a demethylation reaction, wherein R1 and R2 are respectively and independently methyl, ethyl, propyl, naphthenic group, a phenyl and p-methylphenyl. According to the method for preparing azithromycin impurity, the reaction is carried out under a mild condition; the method can be used for preparing the azithromycin impurity I and the azithromycin impurity E by controlling the amount of a reagent; the HPLC purity of the azithromycin impurities prepared by the method is 98 percent or more.
