실험 절차

The solution of 0.500 g of benzyl 3-(2-bromo-3-nitrobenzyloxy)-4-{4-[3-(2-methoxy-benzyloxy)propoxy]phenyl}piperidine-1-carboxylate in 6.5 ml of tetrahydrofuran is cooled to −45° C. under argon and admixed slowly with 4.0 ml of 1-propenylmagnesium bromide (0.5M in tetrahydrofuran). The reaction mixture is stirred over 15 minutes, subsequently poured onto saturated aqueous ammonium chloride solution (10 ml) and extracted with tert-butyl methyl ether (2×25 ml). The organic phases are washed with water (25 ml) and brine (25 ml), dried over sodium sulphate 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=0.21 (1:2 EtOAc-heptane); Rt=6.17.
