Ammonium Acetate → 1-Amino-5-(2-chlorophenyl)cyclohexen-3-one

Participants

Reaction Steps

A solution of 5-(2-chlorophenyl)cyclohexane-1,3-dione (2.5 g) and ammonium acetate (2.6 g) in ethanol (50 ml) was heated under reflux for 12 hours. The solvent was distilled off under reduced pressure, and aqueous sodium hydrogen carbonate was added and the mixture was extracted with ethyl acetate. The organic layer was washed with water and saturated brine, and dried over magnesium sulfate. The solvent was distilled off under reduced pressure, and the resultant crystal was recrystallized from ethyl acetate-hexane to obtain 1-amino-5-(2-chlorophenyl)cyclohexen-3-one (2.2 g) as a pale yellow crystal.
