3-Aminobenzo[cjcinnoline has been prepared from 2,2',4-trinitrobiphenyl and from 2,2'-dmitro-4-ammobiphenyl. The preparations of 1-nitrobenzo[cjcinnoline, x-nitrobenzo [cjcinnoline, and their corresponding amines as reported by Smith and Ruby have been confirmed. The fourth possible isomer, y-nitrobenzo [c jcinnoline, and the corresponding amine have been prepared from benzo [cjcinnoline. In attempts to assign positions to these isomers it was found that 4-dimethylaminoazobenzene could be cyclized to 2-dimethylaminobenzo [c jcinnoline in an eutectic melt of aluminum trichloride.
