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 refluxed for 12 hours. Under reduced pressure, the solvent was evaporated, and to the residue was added sodium hydrogen carbonate solution. The mixture was extracted with ethyl acetate, and the organic layer was washed with water and saturated brine, and dried with magnesium sulfate. Under reduced pressure, the solvent was evaporated to give crystals, which were recrystallized from ethyl acetate-hexane to give pale yellow crystals of 1-amino-5-(2-chlorophenyl)cyclohexen-3-one (2.2 g).
