Procedure

To a -10° C. solution of phenylmagnesium bromide, 3M in ether (68 mL) was added a solution of cupric acetate (5.6 g) and butadiene monoxide (6.43 mL) in THF (200 mL) over 40 min while maintaining the reaction temperature below -5° C. The reaction was stirred at -10° C. for 1 h, room temperature for 16 h, refluxed for 15 min then cooled to room temperature. Aqueous HCl (10%, 100 mL) was added and the mixture extracted with ethyl acetate. The organic solution was washed with aqueous HCl (10%), NaHCO3 (saturated) and brine (saturated), dried (MgSO4) and concentrated to yield a blue liquid. The residue was chromatographed to yield the title compound (6.3 g, 30%).
