To a suspension of 60% sodium hydride (8.79 g) in tetrahydrofuran (500 mL) was added cyclohexanol (10 g) and the mixture was stirred at 0° C. for 0.5 hour. To the mixture was added bromoacetic acid (13.9 g) under ice-water cooling and the mixture was heated under reflux for 2 hours. After adding water to the mixture and organic solvent was evaporated in vacuo. The aqueous solution was diluted with water, washed with ether, acidified with 1 N hydrochloric acid, and extracted with ether. The organic layer was separated, dried over magnesium sulfate, and evaporated in vacuo to give (cyclohexyloxy)acetic acid as colorless oil (13.3 g).
