Benzyl Bromide → Methyl 4-(benzyloxy)-3-methoxybenzoate

참여 물질

반응 단계

Potassium carbonate (3.45 g; 25 mmol) was added to a solution of 4-hydroxy-3-methoxy benzoic acid methyl ester (3.6 g; 20 mmol) and benzyl bromide (3.42 g; 20 mmol) in acetone (100 ml). The reaction mixture was refluxed for 12 hrs. After the removal of the solvent under reduced pressure, the residue was partitioned between ethyl acetate (150 ml) and water (50 ml). The ethyl acetate layer was washed with water (50 ml) and dried over anhydrous magnesium sulfate. Removal of the solvent under reduced pressure provided 4.64 g of 4-benzyloxy-3-methoxy benzoic acid methyl ester (Yield=86.6%)
