Acetic Acid → N-(4-hydroxyphenyl)-4-nitrobenzenesulfonamide
Participants
| Role | Name | HCID | Charge |
|---|---|---|---|
| Reactant | Acetic Acid | HCID 176 | — |
| Reactant | 4-Aminophenol | HCID 403 | — |
| Reactant | 4-Nitrobenzenesulfonyl chloride | HCID 7404 | — |
| Solvent | Pyridine | HCID 1049 | — |
| Product | N-(4-hydroxyphenyl)-4-nitrobenzenesulfonamide | HCID 352935 | 73% |
Reaction Steps
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°.
