Article abstract of DOI:10.1055/s-1990-26894

The reaction of 2-aminobenzoxazoles with benzonitriles in the presence of anhydrous tin(IV) chloride gives N-(benzoxazol-2-yl)benzamidines in high yields.Cyclodehydrogenation of these compounds with lead(IV) acetate affords 2-aryl<1,2,4>triazolo<5,1-b>ben
