Participants

Reaction Steps

A solution of 0.880 g of benzyl 4-{4-[3-(2,5-difluorophenoxy)propoxy]phenyl}-3-{3-oxo-4-[2-(toluene-4-sulphonyloxy)ethyl]-3,4-dihydro-2H-benzo[1,4]oxazin-6-ylmethoxy}piperidine-1-carboxylate and 0.532 g of sodium azide in 10 ml of N,N-dimethylformamide is stirred at 65° C. over 90 minutes. The reaction mixture is poured onto water (40 ml) and extracted with tert-butyl methyl ether (2×40 ml). The organic phases are washed with brine (20 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=0.11 (1:2 EtOAc-heptane). Rt=5.82
