Reaction Steps

5-bromo-3-(5-phenyl-1,3,4-oxadiazol-2-yl)pyrazin-2-amine (150 mg, 0.4715 mmol), [4-(dimethylcarbamoyl)phenyl]boronic acid (91.00 mg, 0.4715 mmol), sodium carbonate (99.95 mg, 0.9430 mmol) and palladium; triphenylphosphane (54.48 mg, 0.04715 mmol) in a mixture of acetonitrile (1.5 mL) and water (1.5 mL) was heated at 110° C. in the microwave for 30 minutes. The reaction was diluted with water and EtOAc and the layers separated. The combined organics were dried (MgSO4), filtered and concentrated in vacuo. The residue was purified by column chromatography (ISCO Companion™, 12 g column, 0-100% EtOAc/Petroleum ether) to give the desired product (102.8 mg, 56% Yield). 1H NMR (400.0 MHz, DMSO) d 2.98 (6H, m), 7.55 (2H, m), 7.69-7.71 (3H, m), 7.83 (2H, br s), 8.17-8.20 (4H, m), 9.00 (1H, s) ppm; MS (ES+) 387.13
