YieldReaction ConditionsOperation in experiment
84% With tetrakis(triphenylphosphine) palladium(0); sodium carbonate; In ethanol; water; toluene; at 120℃; for 1.0h;Inert atmosphere; Microwave irradiation; The product from Example 261B (0.792 g, 3.0 mmol), <strong>[904326-92-7]2-fluoro-3-methylpyridine-5-boronic acid</strong> (Combi-Blocks 0.604 g, 3.9 mmol), tetrakis(triphenylphosphune)palladium(0) (0.173 g, 0.15 mmol) and sodium carbonate (4.50 mL, 9.0 mmol) were combined in toluene (10 mL), ethanol (2.5 mL) and water (2.5 mL), sparged with nitrogen for 10 minutes and heated by microwave at 120 C for 60 minutes. The reaction mixture was partitioned between ethyl acetate and brine. The organic layer was separated, dried (Na2S04), filtered and concentrated. Purification by chromatography (silica gel, 0-60% ethyl acetate in hexane) afforded the title compound (0.742 g, 84%).

YieldReaction ConditionsOperation in experiment
75% Example 261B (2.86 g, 10.8 mmol) and triethylamine (6.03 mL, 43.3 mmol) were stirred in dichloromethane (48.1 mL) at ambient temperature. Methanesulfonyl chloride (2.53 mL, 32.4 mmol) was added dropwise and the solution stirred at ambient temperature for 1 hour. The reaction mixture was concentrated under reduced pressure, dioxane (24 mL) and sodium hydroxide (10 percent w/v, 12 mL, 0.427 mmol) were added, and the solution was heated to 70 °C for 1 hour. The solution was neutralized to a pH of 7 with saturated aqueous NH4CI (200 mL). The aqueous phase was extracted with ethyl acetate (3x125 mL). The combined organics were washed with brine, dried (MgSC^), filtered, then concentrated. The residue was purified by flash chromatography (silica gel, 0-25percent ethyl acetate/hexane gradient,) to afford the title compound (2.79 g, 75percent).
