Example 6 : Preparation of 2-r4-(4-chlorophenoxy)-2-ethylphenyl1cvclopentane-1 ,3-dioneStep 1 : Preparation of (4-bromo-2-ethylphenyl)furan-2-yl methanolMagnesium turnings (1.16g, 0.048mol) are stirred under a nitrogen atmopsphere for 30 minutes, followed by dropwise addition of 4-bromo-2-ethyl-1-iodobenzene (15.Og, 0.048mol) as a solution in anhydrous tetrahydrofuran (40ml), until the magnesium is just covered. A crystal of iodine is added and the reaction heated to reflux. After initiation begins external heating is stopped and the remaining aryl halide solution is added at such a rate as to maintain a controlled reflux. Once addition is complete the reaction is heated at reflux for 1 hour and the mixture is then cooled to room temperature. A solution of furan-2-carbaldehyde (4.0ml, 0.048mol) in anhydrous tetrahydrofuran (10ml) is then added dropwise, and the suspension is then stirred at room temperature for 20 hours. The reaction is quenched with saturated ammonium chloride (200ml) and extracted with ethyl acetate (200ml). The organic phase is separated, dried over anhydrous magnesium sulfate then evaporated under reduced pressure. The crude product is purified by flash column chromatography (1 :4 ethyl acetate/hexane eluant) to afford (4-bromo-2-ethyl- phenyl)furan-2-yl methanol as a brown oil.
