A solution of [6-(2-iodo-oxazol-5-yl)-pyridin-2-yl]-(4-methyl-pyridin-2-yl)-amine (46 mg, 0.121 mmol), phenylboronic acid (30 mg, 0.246 mmol), K2CO3 (37 mg, 0.268 mmol) and Pd(PPh3)4 (14 mg, 0.012 mmol) in a mixture of THF (4 ml) and water (2 ml) was stirred at 90° C. for 18 h. The cooled reaction mixture was treated with water and extracted with EtOAc. The combined organics were dried over MgSO4, filtered and evaporated under reduced pressure before purification by column chromatography on SiO2 eluting with 30% EtOAc in cyclohexane to afford the title compound as a pale orange solid (30 mg, 75%). 1H NMR (DMSO-d6, 300 MHz): δ=9.79 (s, 1H), 8.12 (m, 2H), 8.02 (s, 1H), 7.93 (s, 1H), 7.86 (s, 1H), 7.78 (m, 2H), 7.58 (m, 2H), 7.40 (t, J=7.0 Hz, 1H), 7.33 (t, J=7.0 Hz, 1H), 6.78 (d, J=5.0 Hz, 1H), 2.37 (s, 3H). (ESI+) m/z 329 (M+H)+. Retention time=2.84 mins (method 1).
