실험 절차

4.8 ml of diisobutylaluminium hydride (1.5M in toluene) are added dropwise at −70° C. over 10 minutes to the solution of 1.74 g of tert-butyl 3-[2-(6-chloro-5-methoxycarbonylmethyl-2-methylpyrimidin-4-yloxy)ethoxy]-4-{4-[3-(2-methoxybenzyloxy)propoxy]phenyl}piperidine-1-carboxylate in 20 ml of tetrahydrofuran. The reaction mixture is warmed slowly to −40° C. over 3 hours, admixed with 0.4 ml of methanol and subsequently warmed to room temperature. The reaction solution is admixed with 20 ml of 0.5N HCl and stirred vigorously over 10 minutes. The reaction mixture is extracted with tert-butyl methyl ether (2×). The combined organic phases are washed successively with 1M sodium potassium tartrate solution and brine, dried over sodium sulphate and concentrated by evaporation. The title compound is obtained as a colourless oil from the residue by means of flash chromatography (SiO2 60F). Rf=0.35 (2:1 EtOAc-heptane); Rt=5.75.
