Procedure

A mixture of [6-(2-chloro-oxazol-5-yl)-pyridin-2-yl]-(4-methyl-pyridin-2-yl)-amine (50 mg, 0.174 mmol), K2CO3 (72 mg, 0.523 mmol) and cyclohexanethiol (64 μl, 0.523 mmol) in iPrOH (5 ml) were heated to reflux for 18 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 to a yellow gum. The gum was taken up in a minimum of DCM and precipitated with n-pentane to afford the title compound as a beige solid (45 mg, 71%). 1H NMR (300 MHz, DMSO-d6) δ 9.76 (s, 1H), 8.10 (s, 1H), 7.56-7.78 (m, 4H), 7.17 (d, J=5.9 Hz, 1H), 6.75 (s, 1H), 3.71 (m, 1H), 2.31 (s, 3H), 2.08 (m, 2H), 1.64 (m, 8H). (ESI+) m/z 367 (M+H)+.
