Reaction Steps

The solution of 0.347 g of tert-butyl 3-[1-(2-azidoethyl)-3,3-dimethyl-2,3-dihydro-1H-indol-6-ylmethoxy]-4-{4-[3-(2-methoxybenzyloxy)propoxy]phenyl}piperidine-1-carboxylate in 1.5 ml of tetrahydrofuran is admixed with stirring at room temperature successively with 0.32 ml of water, 1.40 ml of methanol, 0.32 ml of conc. ammonia and 0.210 g of triphenylphosphine, and stirred over 1 hour. The reaction mixture is admixed with water (40 ml) and extracted with tert-butyl methyl ether (2×40 ml). The organic phases are washed successively with water (40 ml) and brine (40 ml), dried over sodium sulphate, filtered and concentrated by evaporation. The title compound is obtained as a yellowish oil from the residue by means of flash chromatography (SiO2 60F). Rf=0.41 (200:20:1 dichloromethane-methanol-conc. ammonia); Rt=5.54.
