The resulting mixture was poured into water and was extracted with diethylether. The extract was washed with water, dried over anhydrous sodium sulfate and concentrated in vacuo. Thus obtained oil was treated with hydrochloric acid to give 1'-(2-phenoxyethyl)-1-methyl-2-oxo-indoline-3-spiro-4'-piperidine hydrochloride
