Procedure

A mixture of ethyl 2-allyl-3-hydroxybenzoate (20.6 g, 100 mmol), benzyl bromide (18 g, 105 mmol), and potassium carbonate (17 g, 123 mmol), was heated in DMF to 100° C. for 18 hr. The mixture was cooled and diluted with water (500 ml), and extracted with ethyl acetate three times. The ethyl acetate extracts were dried over brine and concentrated in vacuo to a tan oil (29.6 g, 100%).
