A method for producing a compound of the formula:
1
(1) in a secondary or tertiary alcohol in the presence of a base, or
(2) in the absence of a base is provided. According to this method, a 1-substituted-1,2,3-triazole compound having a tyrosine kinase inhibitory action can be produced efficiently in a high yield at an industrial large scale by a convenient method

A palladium-catalyzed ortho-acylation of 2-benzyl-1,2,3-triazoles with aldehydes as an acyl source was developed. A wide variety of ketones containing 1,2,3-triazoles were obtained in good to excellent yields. This methodology provides a convenient access to the acylation of 2-substituted-1,2,3-triazoles.
