Reaction Steps

(5-Phenylsulfanyl-pyridine-2-yl)-thiazole-2-yl-amine (0.07 mmol) is dissolved in dichloromethane, cooled to 0° C. and m-chloro-perbenzoic acid (3 eq.) is added. The reaction is stirred 30 min at 0° C. and 22 hours at RT. Sodium disulfite (40 ml) is added and extracted with dichloromethane. The combined organic layers are washed with saturated NaHCO3, dried over MgSO4 and the solvent is removed in vacuo. “A14” is obtained after reversed phase column chromatography (water/acetonitrile) as a colourless powder in a yield of 41%; HPLC (method C): 1.63 min; LC-MS (method A): 1.537 min, 317.95 (M+H+); 1H-NMR (DMSO-d6, 400 MHz): δ [ppm] 11.907 (s, 1H), 8.837-8.829 (m, 1H), 8.146 (dd, 1H, J=2.6 Hz, J=8.9 Hz), 8.006-7.976 (m, 2H), 7.714-7.671 (m, 1H), 7.645-7.605 (m, 2H), 7.456 (d, 1H, J=3.6 Hz), 7.185-7.154 (m, 2H).
