Reaction Steps

To a solution of 2-methoxy-5-(methoxymethoxy)benzaldehyde (10 g, 0.05 mol) in THF (100 mL) was added 3 N HCl (150 mL). The reaction was stirred at 50° C. for 30 min, cooled to rt, and diluted with water (100 mL). The mixture was neutralized to pH 7-8 and extracted with EtOAc (200 mL) three times. The organic layer was dried over Na2SO4 and concentrated to give 5-hydroxy-2-methoxybenzaldehyde.
