Reaction Steps

A mixture of 4-chloro-3-nitro-5-sulphamyl-benzoic acid (28 g), m-chlorophenol (26 g), sodium bicarbonate (34 g), and water (200 ml) was stirred at 85° C for 10 hours. After cooling, excess m-chlorophenol was removed by extraction with diethyl ether, and 4-(m-chlorophenoxy)-3-nitro-5-sulphamyl-benzoic acid was precipitated from the aqueous layer by the addition of 4N hydrochloric acid. After recrystallization from aqueous methanol, the melting point was 230°-232° C.
