A two-step procedure has been developed for the synthesis of 3-alkylquinoxalin-2(1H)-ones from o-phenylenediamine and ethyl 2-oxoalkanoates prepared by the Grignard reaction of diethyl oxalate with alkyl bromides. Analogous reaction with alpha,omega-dibromoalkanes instead of alkyl bromides leads to the formation of 3,3'-(alkane-alpha,omega-diyl)di[quinoxalin-2(1H)-ones].
