Reaction of 2-amino-4-phenyl-5-arylazothiazoles (I) with aryl cyanides in the presence of anhydrous aluminium chloride leads to synthesis of N-2-[4-phenyl-5-arylazo-thiazol-2-yl] aryamidines (ii). These II on oxidative cyclisation with lead tetra acetate yield 4-phenyl-5-arylazo [1,2,4]-triazolo [5,1-b]-thiazoles (IV).
