Versuchsvorschrift
A mixture of 2-(3-benzyloxy4-nitrophenyl)propionic acid(1.89 g), methanol(30 mL) and concentrated sulphuric acid(1 mL) was heated at reflux for 3 h, cooled to ambient temperature and the mixture was extracted with ether. The extract washed with brine, dried and evaporated to dryness to give methyl-2-(3-benzyloxy-4-nitrophenyl)propionate(1.8 g). [m/e316(MH+)].
