Abstract
The present invention relates to a method for preparing the glucopyranosyloxypyrazole derivatives which are useful as agents for the prevention or treatment of a disease associated with hyperglycemia such as diabetes, diabetic complications, obesity or the like. A glucopyranosyloxypyrazole derivative can be easily and efficiently prepared by allowing a benzylpyrazole derivative represented by the general formula: wherein R, R, R, Rand Rmay be the same or different, for example each of them is a hydrogen atom, a halogen atom or an alkyl, alkoxy, arylmethyloxy group or the like, Ris an alkyl group, for example Ris a hydrogen atom or an alkyl, alkoxy, arylmethyloxy group or the like, to react with a compound represented by the general formula: wherein as an example, PGis a pivaloyl group or the like, as an example, Xis a bromine atom or the like, therefore the present invention is extremely useful as a method for preparing pharmaceutical compounds.
