YieldReaction ConditionsOperation in experiment
64.9% To a solution of 2,6-dichloro-4-fluoro-phenol (2 g, 11 .11 mmol) in 20 mL anhydrous DMF was added K2003 (3.07 g, 22.22 mmol) at room temperature. After stirring for 30 mi EtI (3.47 g, 22.22 mmol) was added and the mixture was stirred at room temperature overnight. Waterwas added and the product was extracted with MTBE. The organic phase was washed with brine, dried and concentrated in vacuum to give the crude product, which was purified by column chromatography eluted with 100 % cyclohexane to afford 1 ,3-dichloro-2-ethoxy-5-fluoro- benzene (1 .5 g, 64.9 %).1H NMR (0D013, 400MHz): ö 1.46 (t, J=7.03 Hz, 3 H) 4.07 (q, J=7.03 Hz, 2 H) 7.07 (d, J=7.78 Hz, 2 H).

YieldReaction ConditionsOperation in experiment
72.8% The mixture of <strong>[392-71-2]2,6-dichloro-4-fluorophenol</strong> (362 mg, 2.0 mmol), potassium carbonate (910 mg, 6.6 mmol), ethyl bromoacetate (500 mg, 3.0 mmol) and acetone (25 ml) was refluxed for 12 h. After cooling, the mixture was filtered to remove potassium carbonate. The filtrate was concentrated under reduced pressure. To this residue, 10 ml dioxane and 14 ml 5% sodium hydroxide solution were added. After the mixture was stirred at room temperature overnight, it was acidified with concentrated hydrochloric acid to pH 2, and then extracted three times with ethyl acetate (15 ml each). Organic phases were combined, washed with water and brine, dried over magnesium sulfate, filtered, and then evaporated in vacuo. The residue was recrystallized from ethyl acetate and petroleum ether to give 348 mg 2,6-dichloro-4-fluorophenoxyacetic acid as white crystals, mp 155-158 C., yield: 72.8%. The chemical structure analysis was performed by 1HNMR (Acetone-d6, 600 MHz): δ 7.36 (m, 2H, Ar-H), 4.67 (s, 2H, OCH2CO).

YieldReaction ConditionsOperation in experiment
Example 5. Preparation of 4-Fluoro-2,6-dichlorophenol A mixture of 082 g of 2,6-dichlorophenol, 1.67 g of N-fluoro-2-chloro-6-(trichloromethyl) pyridinium rfluoroborate, and 40 ml of 1,1,2-trichloroethane was placed in a 100 ml 3-necked round bottomed flask equipped with a magnetic stirring bar, a thermometer, and a reflux condenser. The mixture was heated to 55 C. and allowed to react at that temperature for 8 hours under nitrogen. The mixture was then allowed to cool. Analysis by standardized gas-liquid chromatography using a mass spectrometer detector indicated that the title product was present in 24 percent conversion. The product identity was confirmed by its known 19F and 1 H NMR spectra.

YieldReaction ConditionsOperation in experiment
With tributylphosphine; 1,1'-azodicarbonyl-dipiperidine; In toluene; at 100℃; for 1.0h; 2,6-Dichloro-4-fluoro-phenol (39 mg, 0.227 mmol), compound H4 (100 mg, 0.189 mmol) and azodicarboxylic dipiperidide (58 mg, 0.227 mmol) were dissolved in toluene (2 mL), followed by the addition of PBu3 (85%, 54 mg, 0.227 mmol) via syringe under an inert atmosphere. The reaction mixture was heated to 100 0C for 1 h, cooled to rt and Et2O (5 mL) was added. The precipitate was filtered off, the filtrate diluted with EtOAc (10 mL), and the mixture was washed with aq. IM HCl. The org. layer was dried over Na2SO4, filtered, and the solvents were removed under reduced pressure. The crude Boc-protected intermediate of type F was dissolved in a 1:1 mixture of CH3CN/HCO2H, and the mixture was purified by prep. HPLC. The fractions were analyzed and concentrated. The purified Boc-protected intermediate of type F was dissolved in dioxane (0.5 mL), and a sol. of HCl in dioxane (4M, 1 mL) was added. The mixture was shaken for 1 h and then concentrated under reduced pressure. The product was dried under high vacuum to give the title compound (61 mg, 54 % over two steps). LC-MS: tR = 0.97 min; ES+: 593.12.
