Reactions of methyl chloro(phenyl)pyruvate with 1,3-bis(phenylthioureido)benzene easily afforded 1,3-bis(4-hydroxy-4-methoxycarbonyl-3,5-diphenylthiazolidin-2-ylideneamino)benzene. Reactions of the latter with 1,2-phenylenediamines gave various derivatives of thiazolo[3,4-a]quinoxalines, including their bisanalogs.
