반응 단계

A 25-mL 3-neck round bottom flask was charged with 4-nitrophenyl 3-chlorobenzoate (0.64 g, 2.3 mmol), indane-1,3-dione (0.39 g, 2.7mmol) and (methyl sulfoxide)-d6 (5.0 g). The mixture was heated to 80° C. and potassium fluoride (0.60 g, 10 mmol) was added in a single portion. After stirring at 80° C. for 7 hours, the mixture was cooled, partitioned between diethyl ether-ethyl acetate (1:1, 100 mL) and 1N hydrochloric acid (25 mL). The organic layer was washed with additional portions of 1N hydrochloric acid (3×10 mL), then with brine (10 mL), dried over magnesium sulfate, filtered, and evaporated to leave a brown solid (1.05 g).
