Zusammenfassung: | 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.
본 발명은 나트륨-의존성 글루코스 공수송체(SGLT)의 억제제로서 유용한 다이페닐메탄 유도체를 제조하는 개선된 방법에 관한 것으로서, 주요 그룹별로 개별적으로 합성한 뒤 커플링시키는 수렴 합성(convergent synthesis) 방식으로 수행되므로, 종래문헌에 개시된 순차 합성(linear synthesis) 방식에 비해 합성 경로가 간결하고 수율을 높일 수 있으며, 순차 합성 경로가 내재하고 있는 위험요소를 줄일 수 있다. 또한, 상기 방법에 의해 제조된 화합물의 결정형은 물리화학적 특성이 우수하여, 약제 제조 등의 분야에서 유용하게 활용될 수 있다. |
