Abstract A facile, efficient, and economic method toward N-acylbenzotriazoles was reported using 2,4,6-trichloro-1,3,5-triazine in combination with triethylamine as a carboxylic acid activator. Through reacting 1H-benzotriazole with the generated triacylated triazine intermediate, a series of N-acylbenzotriazoles could be rapidly prepared in high yields without column chromatography.

A novel path has been developed for the conversion of carboxylic acids into the corresponding N-acylbenzotriazoles by using 2,2′-dipyridyl disulfide/PPh 3 in anhydrous dichloromethane in the presence of 1 H-benzotriazole. Mild reaction conditio
