Cyclohexanecarbonyl chloride (115 mg) was added and the solution was stirred at room temperature for 16 hours. The solution was diluted with ethyl acetate and washed two times with 1M aqueous HCl and once with brine. The solution was dried on anhydrous sodium sulfate, filtered, and the solvent was removed to provide the title compound which was used without further purification.
