YieldReaction ConditionsOperation in experiment
With potassium carbonate; In N,N-dimethyl-formamide; at 60℃; for 12h; A solution of <strong>[98130-56-4]2-bromo-4,6-difluorophenol</strong> (1.00 g, 4.78 mmol) in DMF (25 ml) was treated with potassium carbonate (3.3 g, 23.9 mmol) and t-butyl bromoacetate (0.85 ml, 5.74 mmol) at 60 C. for 12 hours. The reaction mixture was filtered through celite, and partitioned between water and ethyl acetate. The organic layer was washed with brine, dried over sodium sulfate, filtered and concentrated. The crude was absorbed on silica and purified on a silica gel column with a 5-10% ethyl acetate/hexane gradient to afford a white solid (t-butyl ester). This product was treated with 4 N HCl in dioxane (10 ml) at room temperature for 12 hours. The reaction mixture was concentrated, triturated with hexane, and filtered under suction to afford a white solid (0.92 g, 72%).

YieldReaction ConditionsOperation in experiment
50.5% With potassium carbonate; In N,N-dimethyl-formamide; at 20℃;Inert atmosphere; Example 1.18 To a stirred solution of <strong>[98130-56-4]2-bromo-4,6-difluorophenol</strong> (5.70 g, 1.0 equiv., 27.3 mmol) and ethyl 2-bromo-2,2-difluoroacetate (11.1 g, 2.0 equiv., 54.5 mmol) in DMF (120.0 mL) was added K2CO3 (7.54 g, 2.0 equiv., 54.5 mmol) in portions at room temperature under nitrogen atmosphere. The resulting mixture was stirred overnight at room temperature under nitrogen atmosphere. The mixture was diluted with water (100 mL). The resulting mixture was extracted with EtOAc (3*120 mL). The combined organic layers were washed with brine (2*100 mL), dried over anhydrous Na2SO4. After filtration, the filtrate was concentrated under reduced pressure. The residue was purified by silica gel column chromatography to afford ethyl 2-(2-bromo-4,6-difluorophenoxy)-2,2-difluoroacetate (4.56 g, 50.5%) as an oil. LCMS (ESI): m/z [M+H]+=331.0; 1H NMR (400 MHz, Chloroform-d) δ 7.20-7.24 (m, 1H), 6.93-6.96 (m, 1H), 4.47 (q, J=7.1 Hz, 2H), 1.44 (t, J=7.2 Hz, 3H).
