(Z)-1-Aryl-3-(2-aryl-2-oxoethylidene)piperazin-2-ones react with oxalyl chloride at cooling with the formation of (Z)-2-aryl-8-[hydroxy(aryl)methylidene]-8D degrees-chlorotetrahydropyrrolD 3/4 [1,2-a]pyrazine-1,6,7(2H)-triones. At heating HCl is eliminated from them to produce 8-aroyl-3,4-dihydropyrrolD 3/4 [1,2-D degrees]pyrazine- 1,6,7(2H)-triones.
