Hydrochloric Acid → 3-(Benzyloxy)benzene-1,2-diol

Participants

Reaction Steps

A mixture of 2-methoxy-2-methyl-4-benzyloxy-1,3-benzodioxole (13.6 g., 0.05 mole), methanol (210 ml.) and 5N hydrochloric acid (210 ml.) is stirred under reflux in an atmosphere of nitrogen for 10 hours. Most of the methanol is distilled off under vacuum and the product then extracted with ether. The ethereal solution is washed with water, dried over magnesium sulfate followed by calcium sulfate and evaporated to dryness to yield the crude 3-benzyloxy-catechol which can be recrystallized from di-isopropyl ether.
