Document Type and Number:
WIPO Patent Application WO/2018/004202
Kind Code:
A1
Abstract:
The present invention relates to an improved method for producing a diphenylmethane derivative useful as a sodium-dependent glucose cotransporter (SGLT) inhibitor. Performed in a convergent synthesis manner in which main groups are individually synthesized and then coupled, the method is simpler in synthesis pathway than linear synthesis manners disclosed in prior art documents, and can increase yield and reduce risk factors intrinsic in linear synthesis pathways.
