N-{4-[4-amino-6-(hydroxymethyl)pyrrolo[2,1-f][1,2,4]triazin-5-yl]phenyl}-N′-[2-fluoro-5-(trifluoromethyl)phenyl]urea (40.0 mg, 0.09 mmol) was dissolved in THF (5.0 mL) and to it was added Dess-Martin Periodinane reagent (44.0 mg, 0.10 mmol). The reaction was stirred at rt until HPLC indicated completion of reaction. Reaction was diluted with EtOAc and washed with saturated aqueous NaHCO3/Na2S2O3 1:1 (3×). The aqueous layer was back extracted with EtOAc (2×). Organic was dried (Na2SO4) and evaporated to give a crude oil that was purified via HPLC (10-90% ACN/H2O) to give a yellow solid (35.0 mg, 88%). 1H-NMR (CD3OD) δ 9.76 (s, 1H), 8.61 (d, J=8.0 Hz, 1H), 8.11 (s, 1H), 7.87 (s, 1H), 7.65 (d, J=8.0 Hz, 1H), 7.46 (d, J=8.0 Hz, 1H), 7.30 (d, J=8.0 Hz, 1H); MS [M+H]+=459; LCMS RT=2.95 min.
