Hydrochloric Acid → Methyl 2-hydroxy-4-isopropoxybenzoate

Participants

Reaction Steps

A 1.50 g portion of methyl 2,4-dihydroxybenzoate was dissolved in 30 ml of acetone, and 3.10 g of potassium carbonate and 1.7 ml of isopropyl iodide were added, followed by 48 hours of heating under reflux. After completion of the reaction, the reaction solution was poured into 1N hydrochloric acid aqueous solution, extracted with chloroform and dried over anhydrous sodium sulfate and then the solvent was evaporated under a reduced pressure. The resulting residue was purified by silica gel column chromatography (hexane:ethyl acetate=10:1-2:1) to give 1.60 g of methyl 2-hydroxy-4-isopropoxybenzoate.
