124 g of 2-methoxyphenol and 152 g of potassium carbonate in 500 ml of dimethylformamide are brought to 60° C. with stirring for 30 minutes. 127 g of allyl bromide are introduced and the reaction medium is then left at 60° C. for 1 hour. It is diluted with 2 l of water and extracted with ethyl ether and the organic phase is washed with sodium hydroxide. The organic phase is dried and the ether evaporated off. The product is then distilled at 115° C. and at 20 mmHg to obtain 129.6 g of the expected compound.
