Improved process for preparation of 4-(1-(4-(perfluoroethoxy)phenyl)-1h-1,2,4-triazol-3-yl)benzoyl azide
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.
