250 g (1.86 mol) m-isopropenylphenol and 15 mL (0.19 mol) pyridine were placed in a four-neck flask equipped with a stirrer, reflux condenser, addition funnel, and thermometer. While stirring with cooling on a water bath, 200 mL (2.12 mol) acetic anhydride was dripped in. The reaction mixture was then diluted with ether and washed with water to neutrality. Drying and distillation afforded 310 g (1.76 mol) of the target material. The yield was 94%. The properties of this product are reported below.
