Preparation of the title compound 1 is described.Its treatment with base caused hydrolysis of the amide bond and subsequent benzidine-like rearrangement to give 4'-amino-3-carboxy-4-hydroxy-5-nitrobiphenyl (4).Acid treatment caused cleavage of the nitrogen-oxygen bond and rearrangement to 7-nitro-3-phenylbenzoxazol-2-one (6).
