Reaction Steps

A solution of [6-(2-chloro-oxazol-5-yl)-pyridin-2-yl]-(5-chloro-pyridin-2-yl)-amine (50 mg, 0.162 mmol) in THF (4 ml) and water (2 ml) was treated with 3-thiopheneboronic acid (25 mg, 0.195 mmol), Pd(PPh3)4 (19 mg, 0.0162 mmol) and K2CO3 (50 mg, 0.358 mmol) before heating to 100° C. for 60 h. The cooled mixture was treated with water and extracted with DCM. The combined organics were dried over MgSO4, filtered and evaporated under reduced pressure before purification by column chromatography on SiO2, eluting with 1% EtOH in DCM to afford the title compound as an off-white solid (51 mg, 89%). 1H NMR (400 MHz, DMSO-d6) δ 10.05 (s, 1H), 8.33-8.31 (m, 1H), 8.28 (d, J=2.5 Hz, 1H), 8.15 (d, J=9.0 Hz, 1H), 7.89 (dd, J=9.0, 2.7 Hz, 1H), 7.85 (s, 1H), 7.83-7.77 (m, 2H), 7.69-7.65 (m, 1H), 7.49 (d, J=8.3 Hz, 1H), 7.40 (d, J=7.4 Hz, 1H). (ESI+) m/z 355 (M+H)+. Retention time=4.28 mins (method 1).
