5-Bromo-2-nitrothiophene-3-carboxamide (2.50 g, 9.96 mmol) and 4-[5-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)pyridine-2-yl]morpholine (2.89 g, 9.96 mmol) were combined in THF (40 ml). Tetrakis(triphenylphoshine)palladium(0) (0.58 g, 0.50 mmol) was added and the reaction mixture was heated to reflux overnight. After cooling to room temperature, the mixture was diluted with ethyl acetate (500 ml) and water (500 ml). A red solid crashed out. The mixture was filtered and the solid was washed with ethyl acetate to yield the title compound as a red solid.
