	With dmap; chloro-trimethyl-silane; In tetrahydrofuran; ethyl acetate; 1,1'-carbonyldiimidazole; acetonitrile;	Preparation 8 Ethyl 3-(2,3-difluoro-5-iodophenyl)-3-oxopropanoate (B-3 of Chart B) To a stirred solution of 11.4 g of <strong>[501433-05-2]difluoroiodobenzoic acid</strong> mixture obtained in Preparation 6 in 40 mL of dry THF under argon is added in portions 7.78 g of carbonyldiimidazole and 100 mg of DMAP. The solution is stirred for 18 hours at room temperature. Concurrently, 7.48 g of ethyl potassium malonate is suspended in 40 mL of dry acetonitrile under argon, and to the suspension is added 5.1 mL of chlorotrimethylsilane. The mixture is stirred for 18 h, then cooled to 0 C. for the addition of 12.5 mL of 1,8-diazabicyclo [5.4.0] undec-7-ene. After h, the acyl imidazolide solution is added via cannula, and the resulting mixture is stirred for 1-3 hours. The mixture is then partitioned between ether and excell cold dil. HCl, and the organic phase washed with dil. HCl and brine, and dried (MgSO4). Removal of the solvent under reduced pressure followed by flash chromatography of the residue on silica using 5% ethyl acetate in hepane provides 3.61 g of the title compound as a white crystalline solid. 1H NMR (CDCl3)delta 1.34, 4.28, 5.80, 7.57, 7.95, 12.65 ppm IR 2989, 1652, 1623, 1490, 1421, 1216, 1037, 960, 800 cm-1.

Yield	Reaction Conditions	Operation in experiment
87%	With sulfuric acid; at 0℃; for 6.0h;Inert atmosphere; Reflux;	Embodiment 54 ethyl 2,3-difluoro-4-iodobenzoate 2,3-Difluoro-4-iodobenzoic acid (0.5g, 1.76mmol) was added to a flask, followed by addition of 4mL anhydrous ethanol under argon atmosphere. The mixture was cooled to 0C under an ice bath, then 0.3mL concentrated sulfuric acid was added dropwise. After completion of the dropwise addition, the reaction solution was heated to reflux and stirred for 6 h, meanwhile TLC was used to monitor the reaction. After completion of the reaction, the reaction solution was cooled to room temperature, treated with 1mol/L sodium hydroxide to neutralize sulfuric acid to make a neutral solution, then washed with saturated sodium bicarbonate solution and saturated sodium chloride solution. The organic phase was dried over anhydrous sodium sulfate, filtered, dried, and purified by flash column chromatography (PE:EtOAc = 10:1) to give ethyl 2,3-difluoro-4-iodobenzoate (0.48g, 87%). 1H NMR (500 MHz, CDCl3) delta 7.55 (ddd, J = 8.4, 5.2, 1.8 Hz, 1H), 7.44 (ddd, J = 8.4, 6.3, 1.8 Hz, 1H), 4.38 (q, J = 7.1 Hz, 2H), 1.38 (t, J = 7.1 Hz, 3H). 13C NMR (126 MHz, CDCl3) delta 163.13, 163.10, 163.08, 152.43, 152.31, 150.69, 150.56, 150.46, 150.35, 148.56, 148.44, 133.21, 133.17, 127.48, 127.44, 121.24, 121.18, 88.19, 88.01, 61.98, 14.27.
