%X 2-Dimethylaminobenzo[c]cinnoline is formed when 4-dimethylaminoazo benzene N-oxide is irradiated in 22N sulphuric acid. The same product arises in good yield when 2-chlorobenzo[c]cinnoline is heated with dimethylamine in a sealed tube at 160-170°. A compound formerly described in the literature as 2-dimethyl-aminobenzo[c]cinnoline has now been shown to be 4,4?-bis(4-dimethylaminophenylazo)biphenyl.
