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.
本发明涉及一种生产作为钠依赖性葡萄糖共转运体(SGLT)抑制剂有效的二苯基甲烷衍生物的改进方法,该方法通过聚合合成法进行,其中每个主要基团分别合成,然后偶联。因此,与现有文献中公开的线性合成方法相比,合成途径紧凑,产量可以提高,并且可以减少线性合成途径中固有的风险因素。此外,根据该方法制得的化合物晶体具有极佳的理化特性,因此可有效地用于制药等领域。
