Procedure

6.6 g (0.22 mol) of sodium hydride (80% strength in paraffin oil) are added in portions to 36.0 g (0.2 mol) of 4-hydroxyphenyl 2-hydroxy-2-propyl ketone in 450 ml of dimethyl sulfoxide under an inert gas and the mixture is stirred for 15 minutes at room temperature. 26.8 g (0.22 mol) of allyl bromide in 40 ml of dimethyl sulfoxide are then added dropwise at 30°-40° C., and the mixture is stirred for 15 minutes. The reaction mixture is poured into 2 l of water and then extracted with methyl t-butyl ether. By removing the solvent, 41.5 g of compound IIh are obtained.
