o-Nitroaniline Derivatives. Part 8. Synthesis of Some Unsymmetrical Dimethylquinoxalines: A Long-Standing Problem Resolved

Reduction of N-acetonyl-4-methyl-2-nitro-N-p-tolylsulphonylaniline, using tin(II) chloride in hydrochloric acid, gives 2,7-dimethylquinoxaline (42percent) together with di-p-tolyl disulphide and toluene-p-thiol. 2,6- and 2,5-Dimethylquinoxalines are similarly obtained from the appropriately substituted nitroanilines; the 2,8-dimethyl isomer, however, is obtained impure and in very low yield.
