Reaction Steps
A mixture of 4-chloro-3-nitro-5-sulphamyl-benzoic acid (8.4 g), n-butylamine (8.7 g), and water (25 ml) was stirred at 90°C for 1.5 hours. After cooling, the pH was adjusted to pH 2, and the precipitated 4-butylamino-3-nitro-5-sulphamyl-benzoic acid was collected by filtration. After several recrystallizations from aqueous methanol the melting point was 192.5°C.
