Reaction Steps

Potassium carbonate (1.12 g) was added to a solution of methyl 2,4-dihydroxybenzoate (454 mg) and 2-bromo-4,5-dimethoxybenzyl bromide (1.0 g) in dry acetone (80 ml). The reaction mixture was heated to reflux at 80° C. for 4 hours. The solvents were removed under vacuum and the residue was re-dissolved in DCM and washed with water (3×). The organic layer was passed through a hydrophobic frit and concentrated under vacuum. The crude residue was purified by chromatography on silica gel, eluting with petrol and increasing amounts of ethyl acetate.
