To a stirred 80 g. sample of solid 3-bromobenzofuran is added a large excess of dinitrogen tetraoxide. The mixture liquifies within 5 minutes. After 2 hours, the mixture is triturated with ethanol and filtered to provide yellow crystals of 3-bromo-2-nitrobenzofuran. The product is identical to the product of Example 1 according to infrared spectral analysis.
