The mixture was heated at 60° C. overnight, cooled, diluted with water, extracted twice with dichloromethane, and the organic layers were washed with water. The combined organic layers were dried (Na2SO4), filtered, and evaporated to give crude material which was purified by HPLC (dichloromethane-hexane-ethyl acetate; 48:48:4) to provide 1.08 g of 1-[4-[[2-(cyclooctyloxy)ethyl]thio]phenyl]ethanone as a colorless oil.
