To a suspension of 2.53 g of prewashed 50% sodium hydride in 130 ml of dimethylformamide was added dropwise a solution of 11.99 g of 2-ethyl-4-tetradecylphenol in dimethylformamide. The resulting suspension was heated at 80° C. for 1/2 hour, then allowed to cool and 10.29 g the mesylate of solketal was added. The mixture was heated at reflux for 3 hours, then cooled quenched slowly with water and extracted several times with ether. The ether extracts were combined, washed with brine, dried and the solvents evaporated, giving 16.1 g of the desired compound, mp 34°-38° C.
