Reaktionsschritte

Into a solution of 36 g of 4-methyl-7-hydroxy-1-indanone and 17.6 g of potassium hydroxide in 650 ml of methanol was added 25 ml of allyl bromide, and the mixture was refluxed by heating for 6 hours. The insoluble matters in the reaction mixture were removed by filtration, then the solvent was removed by evaporation. The residue obtained was extracted with chloroform-water, and the chloroform layer was collected by separation, then the solvent was removed by evaporation. The residue thus obtained was washed with ether and purified by means of a column chromatography to obtain 32 g of 4-methyl-7-allyloxy-1-indanone.
