The present invention relates to novel, improved processes for the preparation of sodium glucose co-transporter 2 (SGLT-2) inhibitors and novel intermediates thereof. More particularly, the present invention relates to a novel, improved process for the preparation of gliflozin compounds such as empagliflozin and dapagliflozin, intermediates thereof. The product obtained from the processes of present invention may be amorphous or crystalline, or in the form of amorphous/crystalline solid dispersions/solutions with pharmaceutically acceptable polymers and preparation process thereof. Also, the products obtained from the present invention may be used for the preparation of medicaments for the prevention and/or treatment of diseases and conditions associated with SGLT-2 inhibition.
本发明涉及制备钠葡萄糖共转运体2(SGLT-2)抑制剂及其新型中间体的新型改进工艺。更具体地说,本发明涉及一种制备格列洛嗪化合物(如empagliflozin和dapagliflozin)及其中间体的新型改进工艺。从本发明工艺中获得的产品可以是无定形或结晶,或以无定形/结晶固体分散体/溶液的形式与药学上可接受的聚合物及其制备工艺一起存在。此外,本发明所得产品还可用于制备预防和/或治疗与 SGLT-2 抑制有关的疾病和病症的药物。
