0.22 ml (2.52 mmol) of isopropylamine is added to a solution of 150 mg (0.50 mmol) of 4′-nitrobiphenyl-4-sulfonyl chloride in 2.0 ml of DMF. After 18 h at room temperature, 2.5 ml of water are added to the reaction mixture. The resulting precipitate is filtered off with suction and dried under high vacuum. 126 mg (64.4% of theory) of the title compound are obtained and reacted further without further purification.
