A mixture of 125 g of 3-phenyl-7-nitro-1-naphthol prepared in step (2), 65 g of anhydrous potassium carbonate, 95 g of allyl bromide and 1200 ml of acetone was refluxed for 4 hours with good stirring. After cooling, the mineral salts were removed by filration and the residual organic solution was evaporated to dryness under reduced pressure. The crystals thus formed were washed with petroleum ether, filtered and dried at 80° C. under reduced pressure.
