Procedure

The solution of 2.16 g of tert-butyl 3-(4-allyloxy-3-nitrobenzyloxy)-4-{4-[3-(2-methoxybenzyloxy)propoxy]phenyl}piperidine-1-carboxylate in 15 ml of tetrahydrofuran is admixed with stirring at room temperature with 0.025 g of bis(triphenylphosphine)palladium(II) acetate and 0.075 g of lithium borohydride and stirred at room temperature for 2.5 hours. The reaction mixture is poured onto 1M sodium hydrogencarbonate (50 ml) and extracted with tert-butyl methyl ether (2×50 ml). The organic phases are washed with water (50 ml) and brine (50 ml), dried over sodium sulphate, filtered and concentrated by evaporation. The title compound is obtained as a slightly yellowish oil from the residue by means of flash chromatography (SiO2 60F). Rf=0.38 (1:1 EtOAc-heptane); Rt=6.02.
