    摘要: This invention discloses a method of manufacturing clarithromycin, where an erythromycin A 9-oxime thiocyanate salt is used directly to perform an etherification reaction, and then successively silanizattion, methylattion and hydrolysis reactions are sequentially conducted. It is a new process with simple process with a high yield, low cost, less pollution, high quality and is suitable for commercial manufacturing.
