A solution of ethyl 3-allyl-4-hydroxybenzoate (6.74 g, 32.7 mmol) in chloroform (105 ml) was added with meta-chloroperbenzoic acid (11.40 g, 66.1 mmol) and the mixture was refluxed under stirring for 4 h. Afterwards, the solvent was evaporated, the crude was redissolved in ethyl acetate and washed with a 1M NaOH solution. After drying and removing the solvent, a crude was obtained which was purified by chromatography through a silica gel column, eluting with n-hexane:ethyl acetate, 90:10, to recover 5.95 g of the title compound (82% yield).
