To commercially available nitromethane (5 ml) were added commercially available anisole (0.5 ml), commercially available cyclohexanecarbonyl chloride (0.63 ml) and commercially available ytterbium(III) trifluoromethanesulfonate (288 mg), and the admixture was stirred at 60° C. for 3 hours. The reaction mixture was partitioned between water and chloroform, and the chloroform layer was washed with saturated aqueous sodium hydrogen carbonate and brine and then dried with anhydrous sodium sulfate. After removing the solvent by reduced-pressure distillation, the resulting residue was purified by chromatography on silica gel eluting with chloroform to obtain 517 mg of the title compound (yield: 51%).
