Procedure

4-Methylphenol (5.4g; 0.05 m) and potassium carbonate (6.9g; excess) were mixed in dry acetone (40 ml.) phenacyl bromide (9.95 g.; 0.05 m) was added and the mixture was boiled under reflux with vigorous stirring for 4 hours. The mixture was cooled to room temperature, poured into iced water extracted with ether, washed with dilute sodium hydroxide solution water, dried and evaporated. The crude product was recrystallised from ethanol to give the title compound. m.p. 65° C.
