Arylation Reaction of Cyclic Guanidine‐Analogs with α‐Halo‐ anthraquinones: New Anthrapyrimidines 2‐Amino‐benzimidazole gives on Ullmann ‐reaction with α‐halo‐athraquinones such as 1‐amino‐4‐bromoanthraquinone‐2‐sulfonic acid (la) the new benzimidazo‐anthrapyrimidine 2a , whereas 3‐amino‐ triazole gives under the same conditions two products: the 1,2,4‐triazoloanthrapyrimidine 7 and l‐amino‐4‐(3‐amino‐1,2,4‐ triazolyl)anthraquinone‐2‐sulfonic acid ( 8 ). The new structures were elucidated by 1 H‐ and 13 C‐NMR. and X‐ray analysis.
