    Alcaftadine is an active pharmaceutical ingredient (API) used as an ophthalmic solution for the prevention of itching associated with allergic conjunctivitis. The originally reported synthesis uses a time-consuming column chromatography technique for the isolation of hydroxymethylated product alcohol (10). A simple yet effective double oxidation strategy is developed using oxidation grade manganese dioxide to avoid tedious chromatographic purification. Firstly, a partial oxidation of hydroxymethylated crude mass (mixture of compounds 9, 10 and 16) was carried out using a limited amount of MnO2 to get rid of critical diol impurity (16) and to allow crystallization of alcohol (10) crude, followed by its second oxidation using additional MnO2 to provide alcaftadine via a scale-up friendly process. This synthetic approach has been proven to be cost effective and commercially viable. Various impurities formed during the process were also identified and eliminated to obtain ICH guideline purity of alcaftadine API. The process was validated in plant scale and US DMF was filed to manufacture alcaftadine API.

    阿尔卡法丁是一种活性药物成分(API),用于眼科溶液,用于预防与过敏性结膜炎相关的瘙痒。最初报道的合成方法使用耗时的柱层析技术来分离羟甲基化产物醇(10)。使用氧化级锰矿石的简单而有效的双氧化策略,避免了繁琐的色谱纯化。首先,使用少量MnO2对羟甲基化的粗质量(化合物9、10和16的混合物)进行部分氧化,以去除关键的二醇杂质(16)并允许醇(10)粗品结晶,然后使用额外的MnO2进行第二次氧化,以通过可扩展的过程提供阿尔卡法丁。这种合成方法已被证明具有成本效益和商业可行性。还确定并消除了过程中形成的各种杂质,以获得符合ICH指南的阿尔卡法丁API纯度。该过程已在工厂规模上得到验证,并提交了美国DMF以制造阿尔卡法丁API。
