The present invention relates to an improved method for producing a diphenylmethane derivative which is effective as a sodium-dependent glucose cotransporter (SGLT) inhibitor, the method being carried out by means of a convergent synthesis method in which each major group is separately synthesized and then coupled. As such, in comparison to a linear synthesis method disclosed in existing documents, the synthesis pathway is compact and yield can be increased, and risk factors inherent in the linear synthesis pathway can be reduced. Furthermore, the crystal form of the compound produced according to the method has superb physicochemical characteristics, and thus can be effectively utilized in fields such as pharmaceutical manufacturing.
本发明涉及一种改进的制备二苯甲烷衍生物的方法,该方法作为一种钠依赖型葡萄糖共转运蛋白(SGLT)抑制剂具有高效性,该方法通过收敛合成方法进行,其中每个主要基团分别合成然后耦合。因此,与现有文件披露的线性合成方法相比,合成途径更为紧凑,产率可以提高,并且线性合成途径固有的风险因素可以降低。此外,根据该方法生产的化合物的晶型具有出色的物理化学特性,因此可以有效地应用于制药制造等领域。
