Reaction Steps

N-(2-t-Butoxycarbonylaminophenyl)-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzamide (Method 13; 132 mg, 0.3 mmol), 2-bromopyridine (40 mg, 0.25 mmol), tetrakis(triphenylphosphine)palladium (4 mg, 0.004 mmol), 1,2-dimethyoxyethane (1.5 ml) and a saturated aqueous solution of sodium hydrogen carbonate (1.5 ml) were stirred at 80-85° C. under an atmosphere of argon for 24 hours. The mixture was allowed to cool before being partitioned between ethyl acetate and water. The organics were separated, washed with brine, dried over magnesium sulfate, filtered and evaporated to yield the title compound (86 mg, 74%) which was used in the next reaction without further purification; Mass Spectrum: M+H+ 390.
