IMPROVED PROCESS FOR PREPARATION OF 4-(1-(4-(PERFLUOROETHOXY)PHENYL)-1H-1,2,4-TRIAZOL-3-YL)BENZOYL AZIDE

摘要

By either forming a triaryl acid halide or a triaryl mixed anhydride and subsequently treating with aqueous sodium azide, triaryl acyl azides are prepared in high yield using inexpensive reagents in a process in which by-products are easily removed from the triaryl acyl azide.
