실험 절차

A mixture of 4-aminophenol (27 g, 0.25 mole) and 4-nitrobenzenesulfonyl chloride (55 g, 0.25 mole) in pyridine (500 ml) was heated under reflux for 4 hours. The reaction mixture was poured in ice water and acidified with acetic acid. The crude product weighed 86 g. Recrystallization from CH3NO2 provided 53 g (73%) of material used in Part B; m.p. 197°-198°.
