Procedure

To a solution of 3-bromo-4-hydroxybenzaldehyde (5.0 g, 24.9 mmol; 1 eq) in DCM (10 mL), was added 1-(bromomethyl)-4-methoxybenzene (6.0 g, 29.88 mmol, 1.2 eq, Aldrich, Milwaukee, Wis., USA) and DIEA (8.7 mL, 49.7 mmol, 2 eq). After stirring at room temperature for 18 h, the reaction mixture was diluted with DCM and washed with saturated NaHCO3 and brine. The organic layer was dried (Na2SO4), filtered and concentrated in vacuo to give 8.0 g of 4-(4-methoxybenzyloxy)-3-bromobenzaldehyde (32).
