Versuchsvorschrift

To a solution of 4-(bromomethyl)phenylacetic acid (20 g, 87.3 mmol) in MeOH (200 ml) was added trimethylsilylchloride (2 ml) and the reaction stirred for 2 h. The solvent was removed in vacuo and the residue was twice re-dissolved in MeOH (200 ml) and re-concentrated to give the title compound (21.08 g). δH (CDCl3, 250 MHz) 7.36 (2H, d), 7.26 (2H, d), 4.49 (2H, s), 3.69 (3H, s), 3.62 (2H, s).
