To a solution of [6-(thiazolo[4,5-b]pyridin-2-yloxy)-1H-indol-2-yl]-methanol (0.89 g, 3.0 mmol) in CHCl3 (30 mL) was added MnO2 (2.6 g, 30 mmol) and the reaction mixture was heated (80° C., 3 h). The reaction mixture was cooled (rt), filtered (Celite®) and washed with isopropanol:DCM (15%, 300 mL). The filtrate was dried, filtered and concentrated in vacuo. The resulting residue was purified by reverse phase HPLC to provide the title compound as a colorless solid (139 mg, 16%). MS (ESI): mass calcd. for C16H9N3O2S, 295.0; m/z found, 296.0 [M+H]+. 1H NMR (400 MHz, DMSO-d6): 9.94 (s, 1H), 8.59 (dd, J=4.8, 1.7, 1H), 8.46 (dd, J=8.0, 1.7, 1H), 7.95 (t, J=18.7, 1H), 7.61 (d, J=2.2, 1H), 7.55 (s, 1H), 7.40 (dd, J=8.0, 4.8, 1H), 7.34-7.15 (m, 1H).
