実験手順

A 32.5-g (0.15 mol) sample of 5-chloro-2-thienylsulfonyl chloride was added in small portions to a stirred solution of 150 ml concentrated nitric acid and 150 ml concentrated sulfuric acid. After the addition was completed, the reaction mixture was stirred at about 25° C overnight. The reaction mixture was then diluted with ice water and filtered to give the 5-chloro-4-nitro-2-thienylsulfonyl chloride product.
