Procedure

To 5-(2-fluorophenyl)-3-methyl-4-carbethoxy-2-cyclohexen-1-one (57.3 g, 0.21 mole) was added a solution of sodium hydroxide (11.5 g, 0.29 mole) in 35 ml of ethanol and 80 ml of water. The stirred reaction mixture was heated under reflux for 8 hours. The ethanol was removed by evaporation under reduced pressure, and the residue was extracted with diethyl ether. The ether extract was dried over sodium sulfate and filtered. The filtrate was evaporated under reduced pressure to give 5-(2-fluorophenyl)-3-methyl-2-cyclohexen-1-one (42.3 g).
