Procedure
The mixture of 0.0074 g of 2-(di-t-butylphosphino)biphenyl, 0.017 g of dipalladiumtris (dibenzylidenacetone)-chloroform complex and 0.055 g of sodium tert-butoxide is admixed under argon with the solution of 0.280 g of tert-butyl 3-[chloro-3-(3-methoxypropoxy)benzyloxy]-4-{4-[3-(2-methoxybenzyloxy)propoxy]phenyl}piperidine-1-carboxylate (Example 31a) and 0.043 ml of morpholine in 2.0 ml of toluene. The reaction mixture is stirred at 110° C. over 16 hours, subsequently cooled, poured onto water (20 ml) and extracted with ethyl acetate (2×20 ml). The organic phases are washed with brine (20 ml), dried over sodium sulphate, filtered and concentrated by evaporation. The title compound is obtained as a white foam from the residue by means of flash chromatography (SiO2 60F). Rf=0.23 (2:1 EtOAc-heptane); Rt=5.46.
