A flask was charged with 2,4-bis-benzyloxy-5-bromobenzyl alcohol (10.5 g; 26 mmol), manganese dioxide (45 g; 0.520 mol), and dichloromethane (250 mL). The reaction was stirred at reflux for three days. The slurry was then filtered through celite, and evaporated to give 2,4-bis-benzyloxy-5-bromobenzaldehyde (7.46 g; 18.77 mmol).
