Patent number: 11377465Abstract: A pyranoglucose-substituted pyrazole compound, used as a pharmaceutical intermediate, having the structural formula represented by formula (9c). The present invention further relates to an intermediate compound represented by formula (10c) or a salt thereof. The present invention further relates to a preparation method of the aforementioned intermediate compound and a method of using the same to prepare an SGLT inhibitor. By means of the novel key intermediate, the preparation technique of an SGLT inhibitor is greatly simplified. In addition, because the intermediate can be precipitated in the form of a salt and is easy to purify, the purity of the SGLT inhibitor is significantly increased, compared with the original preparation pathway (crude product purity can reach 99% or more).Type: GrantFiled: January 17, 2019Date of Patent: July 5, 2022Assignees: Yabao Pharmaceutical Group Co., Ltd., Suzhou Yabao Pharmaceutical R&D Co., Ltd.Inventors: Fei Zhang, Peng Wang, Lili Sun, Lin Zhu
