Procedure

4-[(6-Nitro-2-phenyl-4-quinolyl)oxyacetyl]morpholine (12.5 g) in ethanol (550 cc) is heated under reflux for 10 minutes and a solution of sodium dithionite (27.7 g) in water (277 cc) is added in the course of 25 minutes. The mixture is cooled to room temperature (approximately 20° C.) and the ethanol removed under reduced pressure. The aqueous phase is stirred with ethyl acetate and the organic phase is washed with water, dried over magnesium sulphate and evaporated under reduced pressure. The residue obtained is taken up in ethyl ether and converted to the crude hydrochloride by adding a solution of hydrochloric acid in isopropanol. The hydrochloride is taken up with ethyl acetate and aqueous sodium carbonate solution. The precipitate which separates is filtered, heated for 25 minutes in refluxing ethyl acetate, filtered off and dried. 4-[(6-Amino-2-phenyl-4-quinolyl)oxyacetyl]morpholine (1.15 g), m.p. 194° C., is thereby isolated.
