Procedure

351 g of acetic anhydride followed by 2.5 ml of sulphuric acid (d=1.84) in small amounts, and finally, 355 g of methyl 2-hydroxy-3-allyl-4-methylbenzoate were introduced into a 2-liter round-bottomed flask. The temperature rose up to 35° C. The contents were heated under reflux for 3 hours and the solution obtained was then poured into 2 liters of iced water. The oily layer formed was decanted and extracted with ether and the solution containing ether was dried over sodium sulphate.
