Reaction Steps

To a solution of cyclopent-3-ene-1-carboxylic acid (9.63 g, 85.88 mmol) in 143 mL of degassed DMF was added potassium carbonate (14.24 g, 103.06 mmol) and benzyl bromide (11.24 mL, 94.47 mmol). The mixture was stirred for 2 hours at ambient temperature, and then poured into 150 mL of water and extracted with ethyl acetate. The extracts were washed with water and brine, and dried over sodium sulfate. Filtration and concentration under vacuum afforded benzyl cyclopent-3-ene-1-carboxylate as an oil.
