Procedure

A mixture of 5-methyl-3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-1-tosyl-1H-pyrrolo[2,3-b]pyridine (306 mg, 0.74 mmol) and 4-chloro-2-(methylthio)pyrimidine-5-carbonitrile (207 mg, 1.12 mmol) in dioxane (9 mL) was degassed and stirred under nitrogen for 10 minutes. The reaction mixture was treated with potassium carbonate (336 mg, 2.23 mmol) and bis(tri-t-butylphosphine)palladium(0) (38 mg, 0.074 mmol) and degassed again. The reaction mixture and stirred under nitrogen for 10 minutes. Water (1.35 mL) was added and the reaction mixture was degassed and stirred under nitrogen for 2 hours. A suspension was observed. The resulting mixture was filtered and the solid was washed with dioxane and water. The solid was dried in a vacuum oven to afford the title compound as a white solid (282 mg, 87% yield).
