摘要:The present invention relates to a method for producing an intermediate useful for the synthesis of an SGLT inhibitor. According to the present invention, a compound of Chemical Formula 9, which is an important intermediate for a compound of Chemical Formula 1 as an SGTL inhibitor, may be obtained with high yield and high quality. A method for producing the SGLT inhibitor according to the present invention enables production without special facilities such as an ozone generator and thus is also much more economical.
