실험 절차

Into a 500 ml round bottom flask (fitted with a magnetic stirrer), water (200 ml) was mixed with 4-amino-2,6-dichlorophenol hydrochloride (20 g) until the solid was completely dissolved. The resulting solution was warmed to 70° C., and to it was added acetic anhydride (11 g) and the resulting solution was stirred for 1 hour. Upon cooling, crystals of 3', 5'-dichloro-4'-hydroxyacetanilide formed (19.6 g, 95% yield).
