Title:
METHOD FOR PRODUCING COMPOUND
Document Type and Number:
WIPO Patent Application WO/2022/030622
Kind Code:
A1
Abstract:
The present invention provides a method which can produce an intermediate of an azole derivative at lower cost than an existing production method. The method is for producing a compound represented by general formula (IV) and includes a step in which a compound represented by general formula (II) is converted into the compound represented by general formula (IV) in the presence of an inorganic base using both (a) dimethyl sulfide and/or dimethyl sulfoxide and (b) a methyl-LG (wherein LG is a nucleophilically replaceable leaving group and is selected from among halogen groups, alkoxysulfonyloxy groups, aryloxysulfonyloxy groups, alkylsulfonyloxy groups, haloalkylsulfonyloxy groups, and arylsulfonyloxy groups).
