To 500 g (3670 mmole) of 4'-hydroxyacetophenone dissolved in 1000 ml of ethanol was added 450 g (3620 mmole) of 45% aqueous potassium hydroxide. To this mixture was added 650 g (3820 mmole) of 1-iodopropane. The resulting mixture was refluxed for 2 hours, cooled, concentrated in vacuo, and the resulting mixture was dissolved in 1000 ml of diethyl ether and 1000 ml of water. The organic layer was separated, washed with brine adjusted to pH 13 with aqueous sodium hydroxide, dried over anhydrous magnesium sulfate, concentrated in vacuo, and distilled yielding 640 g of the desired compound, bp 110° C. at 0.2 torr.
