Procedure:
A three neck flask was charged with 5-bromonicotinic acid (2 g, 9.90 mmol), 3-chlorophenylboronic acid (1.55 g, 9.90 mmol), a 0.4 M solution of sodiumcarbonate in water (37 mL, 14.8 mmol) and Acetonitrile (37 mL). The solution was degassed under vacuum and tetrakistriphenylphoshine Pd(0) (0.57 g, 0.495 mmol) was added and the reaction refluxed overnight under nitrogen. The reaction was cooled to room temperature and filtered through a celite pad. The filtrate was partially evaporated under reduced pressure and the remaining solution acidified to pH=2 with 1N HCl. The resulting solid was collected by filtration and dried under vacuum. 1H NMR [(CD3)2SO]: δ 9.15-9.05 (m, 2H), 8.45 (s, 1H), 7.85 (s, 1H), 7.80-7.65 (m, 1H), 7.60-7.42 (m, 2H).

Procedure:
1.85 g (40 mmols) of formic acid are introduced into a 50 ml. two-necked flask equipped with an air condenser and a dropping funnel. The flask is cooled on an ice bath and 2 ml. of ethylamine are added dropwise. The reaction mixture is allowed to return to ambient temperature and 2.85 g. (10 mmols) of 1-(3'-trifluoromethylthio-phenyl)-2-propanone are added. The contents of the flask are heated for 14 hours at 160°-170°C., 2 ml. of concentrated hydrochloric acid and 2 ml. of water are added, and the mixture is heated for 3 hours at the reflux temperature. A further 2 ml. of concentrated hydrochloric acid are added and the mixture is heated again at the reflux temperature for 2 hours. The mixture is allowed to cool, water is added and the product is extracted once with 50 ml. of diethyl ether. The aqueous layer is rendered alkaline with sodium hydroxide solution and extracted three times in succession with 50 ml. of diethyl ether each time. The combined ether extracts are washed several times with water, dried over sodium sulphate, and filtered. The ether is evaporated from the filtrate in vacuo on a water bath. The 1.4 g of oily residue are dissolved in anhydrous diethyl ether and a solution of hydrogen chloride in diethyl ether is added until precipitation has ended.

Procedure:
To 5 g of methyl 2-chloro-4-nitrobenzoate in 100 mL of EtOH was added 20 g of Tin (II) Chloride in portions. The reaction was heated to 55° C. and monitored by TLC until complete. Solvent was concentrated and extraction was performed in Ethyl Acetate and water with TEA to reduce emulsions. The organic layer was dried over Magnesium Sulfate, filtered and concentrated to give 3.9 g of methyl 4-amino-2-chlorobenzoate. 1 g of methyl 4-amino-2-chlorobenzoate was cooled to 0° C. in DCM with 485 μL of Pyridine before Methanesulfonyl Chloride was added dropwise. The reaction was allowed to warm to room temperature and stir overnight. Solvent was concentrated and the crude material was dissolved in Ethyl Acetate and extracted with saturated bicarbonate 10′ solution and then brine. The crude material was dried over Magnesium Sulfate, filtered and concentrated to give 1.54 g of methyl 2-chloro-4-(methylsulfonamido)benzoate. 107 μL of 1-bromo-2-methoxyethane and 556 mg of Cesium Carbonate were added to 150 mg of methyl 2-chloro-4-(methylsulfonamido)benzoate in DMF and stirred at room temperature for 16 hours. The reaction mixture was extracted in Ethyl Acetate twice with saturated bicarbonate and once with brine, dried over Magnesium Sulfate, filtered and concentrated to give methyl 2-chloro-4-(N-(2-methoxyethyl)methylsulfonamido)benzoate. 182 mg of methyl 2-chloro-4-(N-(2-methoxyethyl)methylsulfonamido)benzoate was hydrolyzed via Procedure M to yield 169 mg of crude 2-chloro-4-(N-(2-methoxyethyl)methylsulfonamido)benzoic acid. 65 mg of 4-chloro-3-(pyridin-2-yl)aniline was coupled to 2-chloro-4-(N-(2-methoxyethyl)methylsulfonamido)benzoic acid via Procedure G. The crude product was purified by reverse phase HPLC to yield 2-chloro-N-(4-chloro-3-(pyridin-2-yl)phenyl)-4-(N-(2-methoxyethyl)methylsulfonamido)benzamide. MS (Q1) 494 (M)+.

Procedure:
A solution of 0.5 g (1.9 mmol) of 8-chloro-5,10-dihydro-dibenzo[b,e][1,4]diazepin-11-thione in 10 mL of 2-ethoxyethanol was treated with 0.46 g (3.8 mmol) of 3-(2-aminoethyl)pyridine and heated at reflux overnight. The solvent was removed under reduced pressure and the residue taken up in EtOAc and washed five times with H2O, then saturated NaCl solution. Drying over MgSO4 and removal of the solvent under reduced pressure gave the crude product. Recrystallization from acetone/water gave 0.49 g (74% yield) of the product as a yellow solid, mp 195-196° C. The structure was confirmed by NMR and mass spectroscopy. (m+H)+ =349.

Procedure:
To a solution of 77.0 g (0.74 mol) of 2-acetylfluorene in 1.1 l of acetic acid are added at 90° C and under intense stirring, 385 g (1.3 mol) of sodium bichromate during a period of 1 hr to 1 hr 15 min. Thereupon, the reaction mixture is allowed to stand under the same conditions for 4 hours, then poured into 4.6 l of water heated to 90° C and kept overnight at room temperature. The precipitate is filtered off, washed with 900 ml of a 2-percent sulfuric acid till a colorless wash solution appears, and with water until the acid reaction disappears. Then the precipitate is treated under intense stirring, with 540 ml of a 5-percent caustic soda solution heated to 90° C, and let cool down to room temperature. The precipitate is filtered off, washed with water and dried in a drying cabinet at 80° C to obtain 62.5 g of crude 2-acetylfluorenone which is then recrystallized from 1.0 l of benzene for the sake of purity. The yield of 2-acetylfluorenone equals 55.5 g (68.0 wt% as calculated for 2-acetylfluorene or 50 wt.% when calculated for fluorene), m.p. 160°-161.5° C.

Procedure:
To a solution of 3-oxo-heptanoic acid methyl ester (5.0 g, 31.6 mmol) in dry dichloromethane (80 mL) add sulfurylchloride (2.82 mL). Stir the reaction mixture at room temperature for 30 minutes then add water (20 mL) and the reaction mixture extracted five times with portions of 30 mL of dichloromethane. Wash the combined organic extracts with water, saturated aqueous solution of NaHCO3 and brine and then dry over MgSO4. Remove the solvent under reduced pressure to give 2-chloro-3-oxo-heptanoic acid methyl ester (6.0 g), which was used in the next step without further purification. To a solution of 2-chloro-3-oxo-heptanoic acid methyl ester (6.0 g, 31.1 mmol) in ethanol (50 mL) add 4-(trifluoromethyl) thiobenzamide (6.4 g, 31.2 mmol). Heat the reaction mixture to reflux overnight. Remove the solvent under reduced pressure and purify the residue by chromatography on silica gel (eluting with a gradient of n-heptane:ethyl acetate (100:1 to 60:1)) to give 4-butyl-2-(4-trifluoromethyl-phenyl)-thiazol-5-carboxylic acid methyl ester (7.4 g) as a yellow oil.
