A solution of 0.50 g of tert-butyl 4-{4-[3-(2-methoxybenyloxy)propoxy]phenyl}-3-(2-{2-[2-(toluene-4-sulphonyloxy)ethyl]phenoxy}ethoxy)piperidine-1-carboxylate (Example 26b) and 0.55 g of sodium methanethiolate in 5 ml of N,N-dimethylformamide is stirred at 90° C. over 1 hour. The reaction mixture is cooled to room temperature, diluted with tert-butyl methyl ether, washed with saturated aqueous sodium bicarbonate solution, dried with sodium sulphate and concentrated by evaporation. The crude title compound is obtained as a colourless oil from the residue. Rt=6.53.
