Quaternary salt formation of cinnolines

University of British Columbia

This study was initially undertaken with a view to preparing quaternary salts of cinnoline simulating the structure of the alkaloid papaverine. This would be possible by the synthesis of two compounds, viz., 6,7-dimethoxycinnoline and 3,4-dimethoxybenzyl-chloride. Some difficulty has been encountered in the synthesis of the former and from experimental evidence now at hand the latter can be considered to be unstable. Some new examples of quaternary salts of 4-methycinnoline are reported but in general isolation of salts from 4-methycinnoline and benzyl-halides has been found impractical due to their hygroscopic properties.
