Procedure

The solution of 5.1 mg of sodium in 0.5 ml of ethanol is admixed with 0.626 g of benzyl 3-(3-hydroxy-4-methylbenzyloxy)-4-{4-[3-(2-methoxybenzyloxy)propoxy]phenyl}piperidine-1-carboxylate and 15 ml of methyl acrylate and stirred at room temperature over 18 hours. The reaction mixture is concentrated by evaporation, and the residue is admixed with 25 ml of 0.5M HCl (cold) and extracted with tert-butyl methyl ether (2×25 ml). The organic phases are washed with brine (25 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=0.42 (1:1 EtOAc-heptane); Rt=6.00.
