Water → Methyl 3-(propan-2-yloxy)-2-(prop-2-en-1-yloxy)benzoate

Participants

Reaction Steps

Cesium carbonate (2.05 g, 6.2 mmol) was added to a solution of methyl 2-hydroxy-3-(propan-2-yloxy)benzoate (123c, 539 mg, 2.40 mmol) in N,N-dimethylformamide (9.6 mL), causing a thick paste to form. Allyl bromide (0.25 mL, 3.0 mmol) was added and the mixture stirred at room temperature for 1.5 hours. Deionized water (15 mL) was added, and the solution extracted with ethyl acetate (2×20 mL). The combined organic extracts were dried over magnesium sulfate, filtered, concentrated under vacuum, and purified by column chromatography (ethyl acetate/heptane) to give methyl 3-(propan-2-yloxy)-2-(prop-2-en-1-yloxy)benzoate (123d, 474.5 mg, 79% yield) as a colorless oil.
