実験手順
The solution of 3.0 g of 4-{4-[3-(2-methoxybenzyloxy)propoxy]phenyl}piperidin-3-ol in 30 ml of ethyl acetate is cooled to 0° C. with stirring and admixed with 30 ml of saturated aqueous sodium carbonate solution. At 0-5° C., 1.32 ml of benzyl formate are added dropwise. After 10 minutes, the reaction mixture is poured onto water (250 ml) and extracted with ethyl acetate (2×250 ml). The organic phases are washed with brine (1×250 ml), dried over sodium sulphate and concentrated by evaporation. The title compound is obtained as a yellow oil from the residue by means of flash chromatography (SiO2 60F). Rf=0.35 (1:1 EtOAc-heptane); Rt=5.94. m.p. 71-73° C.
