Reaction Steps

To a solution of (4-hydroxy-phenyl)-oxo-acetaldehyde (756 mg) in dry DMF (10 mL) were added 3,4-dichlorobenzylbromide (1.2 g) and potassium carbonate (1.03 g). After 4 hours, the reaction mixture was poured into water (100 mL) and extracted with ethyl acetate (2×50 mL). The organic extracts were combined and washed with brine (2×50 mL) and saturated sodium bicarbonate solution (2×50 mL). The organic layer was dried over sodium sulfate and concentrated under reduced pressure to give [4-(3,4-dichloro-benzyloxy)-phenyl]-oxo-acetaldehyde (1.3 g).
