PROCEDURE

实验过程

A mixture of 4-chloro-3-nitro-5-sulphamyl-benzoic acid (8.4 g), aniline (8.4 g), and water (40 ml) was stirred at 80°C for 2 hours. After the addition of 1N hydrochloric acid (50 ml) and cooling, the precipitated 4-anilino-3-nitro-5-sulphamyl-benzoic acid was collected by suction, washed with water, and recrystallized from aqueous ethanol. The melting point was 261°-262°C.
