Procedure
According to the similar procedure to Synthesis Example 1, by using 5-aminosalicylic acid (500 mg, 3.26 mmole) and 4-nitrophenylethyl bromide (900 mg, 3.92 mmole), 890 mg (50% yield) of 2-hydroxy-5-[2-(4-nitrophenyl)ethylamino]-benzoic acid was obtained as a pale yellow solid. Melting point 234-236° C.
