Abstract

An improved one-pot procedure for the preparation of N-acylbenzotriazoles involves mild reaction conditions and allows the preparation of several derivatives not accessible by the previously reported methods.

Key words

N-acylbenzotriazole - carboxylic acid - benzotriazole - thionyl chloride - acylation reagent
