A PROCESS FOR PRODUCING AN ALKOXY-(TETRAZOL-1-YL)BENZALDEHYDE COMPOUND REPRESENTED BY FORMULA (2)

摘要

A process for producing an alkoxy-(tetrazol-l-yl)benzaldehyde compound represented by Formula (2): wherein A1 is an alkoxy group, and A2 is a hydrogen atom, alkyl group or fluorine-substituted alkyl group, the process comprising reacting a 1-(alkoxyphenyl)-lH-tetrazole compound represented by Formula (1): wherein A1 and A2 are as defined above, with hexamethylenetetramine in a mixed solvent of methanesulfonic and trifluoromethanesulfonic acid, and subjecting the resulting reaction product to hydrolysis by introducing water into the reaction system or introducing the reaction solution into water.
