Reaction Steps

A solution of 4-amino-2-chlorophenol (2.0 g, 13.9 mmol) and acetic anhydride (1.77 g, 17.3 mmol) in water (40 ml) was stirred vigorously for 5 minutes. The reaction mixture was then heated with stirring to 60° C. for 30 minutes, and was then allowed to cool. A pink solid was formed and the precipitate was collected by filtration, washed twice with water, and dried to give 1.8 g (70%) of the subtitle compound.
