The spectral similarities of 10 and 11 substituted 7H-benzimidazobenzisoquinolin-7-ones hinder the identification of the individual isomers.Preparation of the 13-methyl p-toluenesulfonate salts of these compounds has allowed the assignment by the use of NOE techniques.Saturation of the N-methyl caused an NOE at H-12.The coupling pattern of H-12 then provides identification of the compound.
