Versuchsvorschrift

Benzyl bromide (0.34 ml, 0.49 g, 2.89 mmol, 1.5 eq) was added to a stirred suspension of dimethyl 2-hydroxyisophthalate (0.4045 g, 1.92 mmol, 1 eq) and K2CO3 (0.5317 g, 3.85 mmol, 2 eq) in anhydrous DMF (2 ml) under Ar. After 48 h the reaction was diluted with Et2O. The mixture was washed with water (×4), brine (×1), and dried over Na2SO4. The inorganics were filtered off and the solvent was removed in vacuo. Purification via flash chromatography yielded 0.5207 g (1.73 mmol, 90% yield) of dimethyl 2-(benzyloxy)isophthalate.
