Reaction Steps

Concentrated sulfuric acid (1 mL) was added to a solution of cyclopentylacetic acid (5.8 mL, 46 mmol) in anhydrous EtOH (15 mL) and heated to reflux for 3 hours. Thereafter, volatiles were removed under reduced pressure and the residue was diluted with water and ethyl acetate. The organic layer was separated, washed with 5% sodium bicarbonate, brine, dried over Na2SO4, and filtered. After evaporation of solvent under reduced pressure, a syrupy cyclopentylacetic acid ethyl ester was obtained and used in the next step without further purification.
