55.35% B: Preparation of the 3. 4-DIFLUORO-2- (2-FLUORO-4-IODO-PHENYLAMINO)-5-NITRO-BENZOIC acid A stirred solution of 2,3, 4-trifluoro-5-nitrobenzoic acid (400 g, 1.9 mol) in dry THF (6L) under nitrogen was cooled to-58 C and a solution of 2.0 L 1.0 M LIHMDS (1. OU, 2L, 2.0 mol) was added dropwise at-58 C. This reaction mixture (yellow solution turned into yellow orange suspension) was designated as reaction mixture A. In a separate reaction flask, 2-FLUORO-4-IODOANILINE (400G, 1.0 mol) in THF (4L) was cooled TO-58 C under nitrogen and a solution LIHMDS (1. 0M, 3.65L, 3.6 mol) was added dropwise AT-58 C (the yellow solution turned into a white suspension). This reaction mixture was designated as mixture B. Both the reaction mixtures A and B were stirred for 45 min. , maintaining the temperature AT-58 C and mixture A was transferred into reaction mixture B by a canula. The resulting orange suspension was stirred for 1 h AT-58 C, then allowed to warm-up to room temperature and stirred overnight under nitrogen. The reaction mixture was cooled to - 10 C and adjusted to pH 1 by bubbling HCI gas. The white solid separated was filtered through a short bed of CELITE, washed with THF (3L) and the filtrate (brown) was evaporated under vacuum. The residue (yellow orange solid) obtained was triturated with 10% aq. HCI (3L) solution and the solid separated was filtered, washed with 10% aq HCI (2X1L), water (4 X 1.0 L) and the wet solid was taken in toluene (1 L). The toluene solution was evaporated to remove water and the residue obtained was digested in hot methanol (3.0 L), filtered, washed with methanol (2L) then dried to give the title compound as solid (yellow). Yield: 543. 9G (55. 35%).
[00130] Step B: 3,4-Difluoro-2-(2-fluoro-4-iodophenylamino)-5-nitrobenzoic acid:[ 00131] To a solution of 2-fluoro-4-iodoaniline (2.9 g, 11.8 mmoles) in 50 ml anhydrous THF at -60 C, 40 ml of a 1M solution of LHMDS in THF (40 mmoles) is added dropwise. In a separate flask, 2,3,4-trifluoro-5- nitrobenzoic acid (5 g, 22.6 mmoles), previously dissolved in THF (50 ml), is treated, at -60 C, with 25 ml of a 1M solution of LHMDS in THF (25 mmoles). Both solutions are stirred at -78 C for 45 min and the second solution is transferred via cannula to the first reaction mixture. After completion of the addition the resulting mixture is stirred under argon at room temperature for 15 hours. The reaction mixture is quenched with water, then 1N HCl is added (pH = 0-1) followed by brine (100 ml). The crude material is extracted with THF (3 x 100 ml), the organic layers are combined and dried (Na2SO4) and the solvent is removed to give the title compound.

Example 11:; 6-fluoro-2-[(2-fluoro-4-iodophenyl)amino]nicotinic acid; To solution of 2-fluoro-4-iodoaniline (0.82 g, 3.46 mmol) in THF (1OmL) at -780C LiHMDS (6.00 mL, 6.60 mmol) was added. After stirring for 15 min, 2,6- difluoronicotinic acid (0.50 g, 3.14 mmol) was added to the mixture. The mixture was allowed to warm to room temperature until completion. The mixture was washed with NaOH (1 N) and extracted with ether. The aqueous layer was acidified with concentrated HCl and back-extracted with ethyl acetate. The organic layer was concentrated to afford product. Second crop of product was obtained by purifying the THF/ether layer with silica gel chromatography.
