Process for producing imidazole derivatives

摘要

The present invention provides a process for producing a compound of the formula (III): wherein R<1> and R<3> are independently hydrogen or an organic group: R<2> is an organic group; and R<4> is an optionally substituted aryl, by reacting the compound of formula (I): wherein R<1>, R<2>, and R<3> are as defined above, with the compound of formula (II): R<4>-S-Hal wherein R<4> is as defined above and Hal is halogen, in the presence of base.
