Procedure

To a mixture of 36 ml of 2-fluorobenzylzinc chloride (0.5 M sol. in tetrahydrofuran) and 0.008 g of dichlorobis(triphenylphosphine)palladium(II) stirred at 0° C. was added dropwise via a syringe 2.14 ml of cyclohexanecarbonyl chloride. Afterwards, the reaction mixture was stirred at r.t. for 4 h, quenched with an aqueous saturated solution of ammonium chloride (25 ml), extracted with 20 ml of EtOAc, which was dried (Na2SO4) and evaporated to dryness in vacuo affording 3.52 g of the title compound as a crude, which could be used in the following step without further purification.
