Sodium Methoxide → Methyl 2-hydroxy-3-(propan-2-yloxy)benzoate

Participants

Reaction Steps

A solution of 2,2-dimethyl-8-(propan-2-yloxy)-4H-1,3-benzodioxin-4-one (123b, 1.40 g, 5.92 mmol) in methanol (12 mL) was treated with sodium methoxide in methanol (0.5 M, 24 mL, 12 mmol) and stirred at room temperature for 3 hours, 40 minutes. The solvents were evaporated and the residue partitioned between ammonium chloride solution (sat., aq., 20 mL) and ethyl acetate (2×30 mL). The combined organic extracts were dried over magnesium sulfate, filtered, and concentrated under vacuum to give methyl 2-hydroxy-3-(propan-2-yloxy)benzoate (123c, 1.24 g, 93% yield) as a colorless liquid.
