A suspension of 15.0 g of 1-(4-hydroxyphenyl)-2-propanone, 24.6 g of 1-bromopropane and 13.8 g of potassium carbonate in 100 ml of N,N-dimethylformamide was heated for 4 hours at 65°-70° C. After cooling, the reaction mixture was poured into water and extracted with ether. The extract was washed with water, dried and evaporated. The residue was distilled to give 15.2 g of the desired compound as a pale yellow oil, b.p.136°-138° C. (7 mmHg).
