実験手順
To a stirred suspension of 414 parts of 2-bromo-3-nitrobenzoic acid in 653 parts of methylbenzene there were added 440 parts of thionyl chloride. The whole was refluxed for 6 hours, cooled and left overnight. The reaction mixture was treated with activated charcoal, filtered over diatomaceous earth and evaporated. The residual oil was triturated with 396 parts of hexane (2×). The product was filtered off, washed with hexane and dried, yielding 363 parts (81.7%) of 2-bromo-3-nitrobenzoyl chloride (interm. 3).
