    • 3CN (0.05 mL) was added. The reaction mixture was stirred for 30 min at room temperature and then saturated aqueous sodium hydrogencarbonate was added. The mixture was extracted with ether, and the organic layer was washed with water and brine, dried over sodium sulfate. After filtration of the mixture and evaporation of the solvent, the crude product was purified by preparative thin layer chromatography to afford the corresponding ester (42.8 mg, 90%) as a colorless oil.
