The present invention concerns a direct process, without the need to isolate any intermediate, for the preparation of Cefepime dihydrochloride monohydrate of sterile quality (for injective use) comprising a preliminary decolorization step in water of the compound of formula (II) in the presence of base or acid, an acylation step with MAEM in the presence of at least one solvent miscible in water, an extraction step in the presence of a solvent immiscible with water, a decolorization step of the rich water solution containing the dissolved product and, lastly, a crystallisation step of the product with acetone in the presence of hydrochloric acid.
本发明涉及一种直接工艺,无需分离任何中间体,用于制备注射用的Cefepime双氯化物一水合物的无菌质量,包括以下步骤:在水中存在碱或酸的情况下,对式(II)化合物进行预处理脱色步骤;在至少一种可溶于水的溶剂存在下,使用MAEM进行酰化步骤;在与水不相溶的溶剂存在下进行萃取步骤;对含有溶解产品的富水溶液进行脱色步骤;最后,在盐酸存在下,使用丙酮结晶步骤对产品进行结晶。
