Versuchsvorschrift

To a 100 ml round flask were added 1.512 g methyl (4-acetoxy-phenoxy)-acetate dissolved in 50 ml anhydrous methanol, 0.364 g sodium methoxide. The mixture was stirred at room temperature for 1 hour. To the stirred mixture was added dilute HCl to adjust pH to weak acidity. The solvent was removed by evaporation. To the residue was added water. The solution was extracted with ethyl acetate for three times. The extract was dried, filtrated and evaporated to obtain 1.004 g of a brown solid, yield 85%. 1H-NMR (400 MHz, DMSO-d6, δ ppm) δ 3.679 (3H, s), 4.646 (2H, s), 6.672 (2H, d), 6.754 (2H, d), 9.0 (1H, s).
