Reaction Steps

Into a Vial was dissolved 1-(3,4-Difluoro-benzyl)-2-oxo-1,2-dihydro-pyridine-3-carboxylic acid (4-bromo-thiophen-2-ylmethyl)-amide (0.0953 g, 0.217 mmol;), 1-Benzenesulfonyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrrolo[2,3-b]pyridine (100 mg, 0.3 mmol;) and [1,1′-Bis(diphenylphosphino)ferrocene]dichloropalladium(II), complex with dichloromethane (1:1) (28 mg, 0.035 mmol; Strem;) in 1,4-Dioxane (3.69 mL, 47.3 mmol; Acros;). To this was added 2.0 M of Sodium carbonate in water (0.92 mL). The reaction was purged with Ar and sealed. The reaction was heated at 100° C. under an atmosphere of Argon for 2 hours. LC-MS showed the formation of product at 1.80 with the correct mass 661.13. The reaction was worked up by dissolving in methylene chloride then washing 1× with citric acid, 1× with saturated bicarbonate and 1× with brine before drying with magnesium sulfate and concentrating to give the crude product. The crude was then purified by combiflash using a 0-100 percent hex/ea gradient to give pure product. ES (+) MS m/e=661.13
