The mixture was made alkaline by addition of 32% sodium hydroxide solution and was extracted with ethyl acetate. The organic phase was washed with water, dried over a deshydrant, filtered and evaporated to dryness. The residue was chromatographed over silica and eluted with a 9-1 ethyl acetate-triethylamine mixture to obtain 3.76 g of N-[2-{2-(3-[3-chloro-1H-indol-4-yl]-propyl)-phenoxy}-ethyl]-2-methyl-2-propanamine.
