180 g. of 1-butyryloxy-3,5-dimethyl-benzene are treated at room temperature with 340 g. of aluminium chloride. The mixture is stirred for 4 hours at 90°-95° C., then cooled at 70° C., poured onto ice and 3 n aqueous hydrochloric acid and extracted with ether. The ether extract is washed with water to neutral reaction, dried over sodium sulfate and evaporated. There is obtained 2-butyryl-3,5-dimethyl-phenol, which melts at 48°-52° C. after recrystalization from petroleum ether.
