Abstract 1-(Benzotriazol-1-yl) alkyl esters 2a-u were obtained in yields averaging 86% by the direct reaction of various aldehydes with the corresponding N-acylbenzotriazoles in the presence of a catalytic amount of potassium carbonate (10–25 mole%). The procedure was optimized by evaluating the effects of solvent, catalyst, temperature and other parameters.
