Procedure:
2-bromo-5-methylpyridine (11.25 g, 65.39 mmol), phenylboronic acid (9.5 g, 78.47 mmol), 2-dicyclohexylphosphino-2′,6′-dimethoxybiphenyl (1.0 g, 2.61 mmol), and potassium phosphate tribasic (45 g, 196.17 mmol), 250 mL of toluene and 25 mL of water were placed in a 500 mL round-bottom flask. Nitrogen was bubbled directly into the mixture for 30 min after which tris(dibenzylideneacetone) dipalladium(0) (598 mg, 0.653 mmol) was added. Nitrogen was bubbled for another 15 min then the reaction mixture was heated to reflux for 16 h under nitrogen. The mixture was cooled and the organic layer was separated from the aqueous layer. The organic layers are washed with saturated brine solution, dried over magnesium sulfate, filtered, and the solvent removed under vacuum to give an off-white solid as the crude. The crude was purified by column chromatography using silica gel as the stationary phase and 5%-10% ethyl acetate in hexanes as the mobile phase. 10.11 g of desired product was obtained after purification (92% yield).

Procedure:
4-nitro-phenylisothiocyanate (43 mg; 1.2 eq.) is added to a solution of benzyl (2S)-2-[(1H-indol-3-ylmethyl)amino]-4-(4-phenyl-1H-imidazol-2-yl)butanoate (93 mg; 1 eq.) in THF (2 ml). The mixture is stirred for 2 hours at approximately 20° C. then diluted with 4 ml of THF. Aminomethylpolystyrene resin (acquired from Novabiochem, load 3.2 mmol/g, 125 mg, 2 eq.) is added, then triethylamine (200 μl). The mixture is stirred for 15 hours at approximately 20° C. then filtered on frit. The filtrate is concentrated to dryness under reduced pressure at 40° C. (a co-evaporation with dichloromethane is necessary to eliminate the excess triethylamine). Purification of the residue by flash chromatography on silica gel (eluent: ethyl acetate/heptane 9:1) yields the expected compound (90 mg; 84% yield).

Procedure:
Under an argon atmosphere and at −78° C., n-butyl lithium (a 1.57M hexane solution, 600 μl, 0.942 mmol) was added to a tetrahydrofuran solution (4 ml) of the 3-[(4-chlorophenyl)sulfonyl]-3-(2,5-difluorophenyl)-1-propanol (300 mg, 0.865 mmol) obtained in Example 207. After stirring for 5 minutes, methanesulfonyl chloride (70.6 μl, 0.908 mmol) was added. The resulting solution was stirred for further 5 minutes and then, n-butyl lithium (a 1.57M hexane solution, 601 μl, 0.944 mmol) was added thereto. The temperature of the reaction mixture was elevated to room temperature, at which stirring was conducted for 18 hours. After cooling to −78° C., n-butyl lithium (a 1.57M hexane solution, 400 μl, 0.255 mmol) was added. The reaction mixture was stirred at room temperature for 3 hours. Water was added, followed by extraction with ethyl acetate. The extracts were combined, washed with brine, dried over magnesium sulfate and then, concentrated. The residue thus obtained was subjected to flash chromatography on a silica gel column, and the fraction obtained from the hexane:ethyl acetate=19:1 eluate was concentrated. The solid thus obtained was recrystallized from ethyl acetate-hexane, whereby the title compound (161 mg, 0.489 mmol, 57%) was obtained as colorless plate crystals.

Procedure:
A mixture of 3-cyclopropyl-2-ethoxymethylene-1-(2-phenylsulphenyl-4-trifluoromethylphenyl)propan-1,3-dione (7 g), hydroxylamine hydrochloride (1.24 g) and sodium acetate (1.5 g) in ethanol was stirred at 25° C. for 2 hours. The mixture was then poured into water and extracted with ethyl acetate. The solution was dried over anhydrous sodium sulphate and filtered. The filtrate was evaporated and the residue purified by column chromatography on silica, using a mixture of ethyl acetate and hexane as eluent. The resulting solution was evaporated and the residue crystallized from cyclohexane to give 3.06 g of 5-cyclopropyl-4-(2-phenylsulphenyl-4-trifluoromethylbenzoyl)isoxazole (compound 1), m.p. 115° C.
