In this paper we describe two new basic conditions for the synthesis of quinoxaline 1,4-dioxide derivatives in moderate to good yields. These conditions, exemplified by the use of K2CO3 in acetone or KF/Al2O3 in the absence of an organic solvent, were reproducible and applicable to the synthesis of 2-(carboethoxy)-3-phenylquinoxaline 1,4-dioxide derivatives substituted in position 4 with electron-donating or electron-withdrawing groups.
