Reaction Steps

The mixture of 3-oxo-cyclopentanecarboxylic acid (750 mg), of benzyl alcohol (633 mg), 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide hydrochloride 1 (680 mg), and of 1-hydroxybenzotriazole (350 mg) in 50 ml tetrahydrofuran was stirred overnight. After addition of aq. Sodium bicarbonate (sat. 25 mL), the reaction mixture was extracted with of ethyl acetate (50 ml×2). The organic layer was washed with brine, dried with anhydrous sodium sulfate and concentrated to yield 3-oxo-cyclopentanecarboxylic acid benzyl ester as oil.
