Reaction Steps
A mixture of 4-chloro-3-nitro-5-sulphamyl-benzoic acid (10 g), n-butanol (100 ml), and conc. sulphuric acid (2ml) was refluxed for 4 hours, during which 50 ml of the solvent were distilled off slowly. After cooling, the n-butyl-4-chloro-3-nitro-5-sulphamyl-benzoate was isolated by filtration and recrystallized from n-butanol. The compound was obtained with a melting point of 140°-141° C.
