Hydrochloric Acid → (8-Methoxy-2,3-dihydro-1,4-benzodioxin-6-YL)methanol

Participants

Reaction Steps

To 30 mL of a tetrahydrofuran solution containing 1.06 g of methyl 8-methoxy-2,3-dihydro-1,4-benzodioxin-6-carboxylate, 720 mg of lithium aluminum hydride was added under cooling with ice. The reaction mixture was stirred at room temperature for 1 hour, 5 mL of a 1 mol/L hydrochloric acid and 45 mL of water were added thereto, and the resultant solution was extracted with ethyl acetate. The organic layer was washed with an aqueous saturated sodium chloride solution and dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure to obtain 940 mg of a brown oily substance, (8-methoxy-2,3-dihydro-1,4-benzodioxin-6-yl)methanol.
