Allyl bromide → Methyl 2-hydroxy-4-[(prop-2-en-1-yl)oxy]benzoate

Participants

Reaction Steps

Methyl 2,4-dihydroxybenzoate (25 g, I48.7 mmol), allyl bromide (18.2 g, I50 mmol), and potassium carbonate (30.8 g, 22.3 mmol) were added to about 250 ml of acetone and the reaction mixture was refluxed with stirring overnight. The reaction mixture was filtered and concentrated. Separation of the pure compound was achieved by chromatography on silica gel using a Waters Prep 500™ and a 20% ethyl acetate/80% hexane solvent system.
