1‐(4‐Chlorophenyl)‐2‐methyl‐3‐phenylquinoxalinium perchlorate ( 5 ) obtained by two different routes, on treating with nucleophiles HX or X − yielded 1,3‐diaryl‐2‐methyl‐2X‐1,2‐dihydroquinoxalines 10 . Alkylation of 10e yielded 4‐(4‐chlorophenyl)‐1,3‐dimethyl‐3‐nitromethyl‐2‐phenyl‐3,4‐dihydroquinoxalinium perchlorate ( 11e ). The 1 H‐nmr and mass spectra are presented. Diastereoisomerism of the products is discussed.
