Procedure
The solution of 0.268 g of tert-butyl 3-[1-(2-aminoethyl)-3,3-dimethyl-2,3-dihydro-1H-indol-6-ylmethoxy]-4-{4-[3-(2-methoxybenzyloxy)propoxy]phenyl}piperidine-1-carboxylate in 0.061 ml of triethylamine and 9.0 ml of dichloromethane is cooled to 0° C. and admixed slowly with the solution of 0.033 ml of acetyl chloride in 1.0 ml of dichloromethane. The reaction solution is stirred over a further 30 minutes, poured onto ice-water (20 ml) and extracted with tert-butyl methyl ether (2×20 ml). The organic phases are washed successively with water (20 ml) and brine (20 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=0.73 (200:20:1 dichloromethane-methanol-conc. ammonia); Rt=5.82.
