Conditions

Temperature: 200 °C

Procedure

3-chlorophenyl acetate (starting material 2) was mixed with aluminium chloride (3 eq). The mixture was heated at 200° C. for 1 hour. The reaction medium was cooled to room temperature then poured in ice. The aqueous phase was extracted with methylene chloride which was dried on magnesium sulfate then vacuum evaporated.
