Reaction Steps

3-bromo-5-(4-(isopropylsulfonyl)phenyl)pyrazin-2-amine (75 mg, 0.2105 mmol), 6-ethynylpyridin-2-amine (29.84 mg, 0.2526 mmol), Pd EnCat 30 (33.68 mg, 0.01347 mmol) and DBU (70.50 mg, 69.25 μL, 0.4631 mmol) were combined in acetonitrile (1.500 mL). The reaction mixture was heated at 100° C. under microwave conditions for 1.5 hours. After this time the solid residue was removed by filtration and the filtrate concentrated in vacuo. The residue was purified by column chromatography (ISCO Companion™, 12 g column, eluting with 0 to 100% EtOAc/Petroleum Ether to 10% MeOH/DCM) to give the titled product as a beige solid (21 mg, 26% Yield). 1H NMR (400.0 MHz, DMSO) δ 1.18 (d, 6H), 3.45 (sept, 1H), 6.20 (s, 2H), 6.52 (d, 1H), 7.06 (d, 1H), 7.07 (br s, 2H), 7.45 (dd, 1H), 7.90 (d, 2H), 8.25 (d, 2H) and 8.78 (s, 1H) ppm; MS (ES+) 394.1.
