Reaction Steps

The solution of 0.108 g of benzyl 4-{4-[3-(2-methoxybenzyloxy)propoxy]phenyl}-3-prop-2-ynyloxypiperidine-1-carboxylate, 0.098 g of N-(2-iodophenyl)methanesulphonamide in 0.5 ml of N,N-dimethylformamide and 1.0 ml of triethylamine are admixed with stirring with 0.011 g of bis(triphenylphosphine)palladium(II) chloride and 0.005 g of copper(I) iodide. The reaction mixture is stirred at 80° C. over 20 hours, then cooled, admixed with water (5 ml) and extracted with ethyl acetate (3×5 ml). The organic phases are washed with brine (1×5 ml), dried over sodium sulphate, filtered and concentrated by evaporation. The title compound is obtained as an orange oil from the residue by means of flash chromatography (SiO2 60F). Rf=0.13 (1:2 EtOAc-heptane); Rt=6.07.
