实验步骤: Dioxane (100 mL) was purged with nitrogen gas for 10 minutes. Phenanthrolene (1.0 g) and copper (I) iodide (1.0 g) were added to the dioxane, the suspension was allowed to stir under a nitrogen atmosphere for 5 minutes, and then cesium carbonate (18.72 g, 57.45 mmol), dimethyl malonate (5.46 g, 50.6 mmol), and 1-iodo-3-(trifluoromethyl)benzene (12.5 g, 46.0 mmol) were added. The reaction mixture was heated to reflux for 18 hours and then cooled to room temperature. Aqueous 1N HCl was added to the reaction mixture, the layers were separated, and the aqueous layer was extracted with ethyl acetate (3×100 mL). The combined organic layers were dried over magnesium sulfate and filtered. Celite® diatomaceous filter aid (5 g) was added to the filtrate, and the resulting suspension was concentrated under reduced pressure at 50° C. to yield a solid consisting of the crude product adsorbed onto Celite®. This solid was purified by silica gel chromatography eluting with a gradient of 100% hexanes to 25% ethyl acetate in hexanes to yield 7.36 g (58.0%) of the title product. 1H NMR (CDCl3) δ 7.59-7.65 (m, 3H), 7.49 (t, 1H), 4.70 (s, 1H), 3.76 (s, 6H).

实验步骤: A solution of 2-propylmagnesium chloride in THF (1.3 M, 7.5 ml) was cooled to −15° C. and admixed with 1-iodo-3-(trifluoromethyl)benzene (2.80 g, 10.2 mmol). The reaction mixture was stirred at −15° C. for 1 h, warmed to room temperature and admixed dropwise with a solution of 2,2-difluoro-N-methoxy-N-methylpropanamide (1.43 g, 9.35 mmol; prepared according to Synth. Comm. 2008 (38), 1940-1945), and stirred at room temperature overnight. Then the mixture was added to ice-cold dilute hydrochloric acid and extracted with ethyl acetate. The combined organic phases were dried over sodium sulphate and concentrated under reduced pressure. The residue was purified by means of silica gel chromatography with the eluent cyclohexane/ethyl acetate (EA) (0% EA to 30% EA). warmed to room temperature stirred at room temperature overnight Then the mixture was added to ice-cold dilute hydrochloric acid extracted with ethyl acetate The combined organic phases were dried over sodium sulphate concentrated under reduced pressure The residue was purified by means of silica gel chromatography with the eluent cyclohexane/ethyl acetate (EA) (0% EA to 30% EA)
