Abstract

The reactions of 4-aroyl-1-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)-5-(methoxycarbonyl)-1H-pyrrole-2,3-diones with p-aminoazobenzene leads to the formation of methyl 3-aroyl-1-(1,5-dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-yl)-4-hydroxy-5-oxo-2-[4-(phenyldiazenyl)benzyl]-2,5-dihydro-1H-pyrrole-2-carboxylates.
