Versuchsvorschrift

3-Phenyl-1-isoquinolinepropanoic acid (6.7 g) and concentrated sulphuric acid (7 cc) in ethanol (0 cc) are stirred for 20 hours at 20° C. The solution is poured into water (400 cc) and the aqueous phase alkalinised with concentrated ammonia solution. The mixture is extracted with methylene chloride (3×100 cc), and the organic phase dried and evaporated to dryness under reduced pressure. Ethyl 3-phenyl-1-isoquinolinepropionate (6.3 g), m.p. 60° C., is obtained.
