PROCEDURE

实验过程

A solution of 2.0 g of tert-butyl 4-{4-[3-(2-methoxybenzyloxy)propoxy]phenyl}-3-(2-{2-[2-(toluene-4-sulphonyloxy)ethyl]phenoxy}ethoxy)piperidine-1-carboxylate (Example 26b) and 1.32 g of sodium azide in 20 ml of N,N-dimethylformamide is stirred at 65° C. over 90 minutes. The reaction mixture is diluted with semisaturated aqueous sodium hydrogencarbonate solution and extracted with tert-butyl methyl ether (3×). The combined organic phases are dried over sodium sulphate and concentrated by evaporation. The crude title compound is obtained as a colourless oil from the residue. Rf=0.43 (1:1 EtOAc-heptane); Rt=6.40.
