Versuchsvorschrift

A stirred solution of (2R)-1-(3'-cyanobiphenyl-4-yloxy)-4-(3-pyridyl)-2-butanol (0.60 g) and sodium hydroxide (0.696 g) in ethanol (8 ml) and water (2 ml) was heated at reflux for 10 hours. The mixture was concentrated and the residues dissolved in water and neutralised. The precipitate was filtered off and dried under vacuum to give the title compound as a white solid (0.616 g).
