실험 절차

To commercially available nitromethane (10 ml) were added commercially available anisole (1.081 g), commercially available 2-thenoyl chloride (1.466 g) and commercially available ytterbium(III) trifluoromethanesulfonate (620 mg), and the admixture was stirred at 60° C. for 8 hours. The reaction mixture was treated in the same manner as described in Example 35 to obtain 965 mg of the title compound (yield: 44%).
