Benzyl Bromide → 3-Benzyloxy-4-methoxybenzaldehyde

Participants

Reaction Steps

To a solution of isovanillin (200 g) in dimethylformamide (500 ml) is added potassium carbonate (236 g) under ice-cooling, and thereto is added dropwise benzyl bromide (203 ml), and the mixture is stirred overnight. The insoluble materials in the resulting residue are removed by filtration, and washed with acetone, and the filtrate is concentrated under reduced pressure to remove the solvent. The residue is washed again with ether and water, and concentrated under reduced pressure to remove the solvent to give 3-benzyloxy-4-methoxybenzaldehyde as an oily product.
