実験手順

4.45 g (50 mMol) 2-Amino propanoic acid were added to 9.7 (51 mMol) p-toluenesulphonic acid and 20 ml (193 mMol) Benzyl alcohol in 10 ml toluene. The reaction mixture was heated under reflux for 2 h using a water separator. 30 ml dichloromethane was added to the cooled reaction mixture. The product was purified by flash chromatography using CH2Cl2:CH3OH 50:1.
