Reaction Steps
A mixture of 5-bromo-3-(5-phenyl-1,2,4-oxadiazol-3-yl)pyrazin-2-amine (100 mg, 0.3143 mmol), (4-methylsulfonylphenyl)boronic acid (94.29 mg, 0.4714 mmol) and PdCl2(PPh3)2 (11.03 mg, 0.01572 mmol) in DMF (2 mL) was treated with Na2CO3 (471.4 μL of 2 M, 0.9429 mmol) and the reaction placed under an atmosphere of nitrogen and heated at 110° C. in a sealed tube for 16 hours. The resultant precipitate was filtered, washed with water and dried under vacuum (83 mg, 67% Yield).
