实验步骤: A mixture of 1,2-bis(4-fluorophenyl)-1-oxoethane (2.13 g) and ammonium formate (3.78 g) was stirred for 10 hours at 190° C. After cooling, concentrated hydrochloric acid (12 ml) was added to the reaction mixture and the mixture was refluxed for 5 hours. After cooling, aqueous sodium hydroxide solution was added to the mixture and alkalized. The product was extracted with ethyl acetate and the organic layer was washed with saturated sodium chloride solution. The organic layer was dried over anhydrous magnesium sulfate and concentrated in vacuo. The oily residue was dissolved in methanol. To the solution, HCl/methanol was added and the solution was concentrated in vacuo. Separated crystals were collected by filtration to give 1.77 g (65.6%) of the titled compound. After cooling the mixture was refluxed for 5 hours After cooling The product was extracted with ethyl acetate the organic layer was washed with saturated sodium chloride solution The organic layer was dried over anhydrous magnesium sulfate concentrated in vacuo The oily residue was dissolved in methanol To the solution, HCl/methanol was added the solution was concentrated in vacuo Separated crystals were collected by filtration

实验步骤: SeO2 (191 mg, 1.72 mmol, 4.00 equiv) was added in batches to a solution of 1,2-bis(4-fluorophenyl)ethanone (100 mg, 0.43 mmol, 1.00 equiv) in DMSO (4.5 mL). The resulting solution was allowed to react, with stirring, for 2 hrs while the temperature was maintained at 100° C. in an oil bath.

实验步骤: A solution of 2-(4-fluorophenyl)acetic acid (5.0 g, 32.5 mmol, 1.00 equiv) in SOCl2 (30 mL) was heated for 3 hr at reflux in a 50-mL round-bottom flask. Most of SOCl2 was removed under vacuum, and the residue was added dropwise into a solution of AlCl3 (12.8 g, 96.2 mmol, 3.00 equiv) and fluorobenzene (6.1 g, 63.54 mmol, 2.00 equiv) in DCM (20 mL) at 0° C. The resulting solution was allowed to react, with stirring, for 2 hrs at room temperature. at reflux in a 50-mL round-bottom flask Most of SOCl2 was removed under vacuum to react
