METHOD FOR PRODUCING 1-SUBSTITUTED-1,2,3-TRIAZOLE DERIVATIVE

摘要

A method for producing (I) or (II), characterized in that (III) and (IV) are reacted (1) in a secondary or tertiary alcohol in the presence of a base or (2) in the absence of a base. The method can be employed for producing a 1-substituted-1,2,3-triazole compound having inhibitory action for tyrosine kinase, in a high yield and with a simple and easy process, on a commercial scale.
