| Reactant | Acetic Anhydride | HCID 7918 | — |
| Reactant | 2-Amino-5-chlorophenol | HCID 91591 | — |
| Solvent | Methanol | HCID 887 | — |
| Product | N-(4-Chloro-2-hydroxyphenyl)acetamide | HCID 177739 | 91.6% |
Reaction Steps
To a suspension of 2-amino-5-chlorophenol (1.01 g, 7.0 mmol) in methanol (10 mL) was added acetic anhydride (1.08 g, 10.55 mmol) and the reaction mixture was stirred at room temperature for 30 min. The volatiles were removed in vacuo and the residue was purified by silica gel flash chromatography (hexane:ethyl acetate 5:2) to give the subtitled compound (1.19 g).
