反应详情

A mixture of 3-aminophenol (33 g, 0.3 mole) and p-nitrobenzenesulfonyl chloride (66 g, 0.3 mole) in pyridine (350 ml) was heated at 80° on a steam bath for 4 hours. The reaction mixture was poured on ice and acidified with acetic acid. The precipitated product was filtered and recrystallized from isopropanol and gave 50 g (49%) of product which was used in Part B.
