Versuchsvorschrift

To a solution of 300 mg of (S)-2-(6-methoxy-2-naphthyl)-propionic acid in 5 ml of methanol is added a 1 molar equivalent of sodium hydroxide, in the form of a 0.1N solution. The solvent is evaporated in vacuo and the residue is taken up in 2 ml of methanol, followed by precipitation with ether, to yield crude sodium (S)-2-(6-methoxy-2-naphthyl)propionate.
