Reaction Steps

To a solution of 4-(6′-chloro-3,4,5,6-tetrahydro-2H-[1,4′]bipyridinyl-2′-ylamino)-N-methyl-benzenesulfonamide (70 mg, 0.18 mmol) in 1,4-dioxane (8 mL) was added sodium carbonate (1N, 80 mg, 0.72 mmol), and tetrakis(triphenyl-phosphine)palladium(0) (21 mg, 0.018 mmol), followed by 4-fluorophenyl boronic acid (49 mg, 0.36 mmol). This reaction was refluxed for 8 hours, after which time water (100 mL) added to the reaction mixture, and the product was extracted with ethyl acetate (100 mL×3). The organic layer was dried over sodium sulphate, filtered, and the filtrate was and concentrated under vacuum. The resulting product was purified through column chromatography using 230-400 mesh silica gel (5% methanol in dichloromethane) to afford the desired compound as A yellow solid (48 mg, Yield 60%). Purity: 98.2%.
