Participants

Reaction Steps

To a solution of THF (5 mL) was added N-{4-[4-amino-6-(3-hydroxypropyl)pyrrolo[2,1-f][1,2,4]triazin-5-yl]phenyl}-N′-[2-fluoro-5-(trifluoromethyl)phenyl]urea (55 mg, 0.11 mmol) followed by Dess-Martin Periodinane reagent (0.29 mL, 0.14 mmol, 15% wt in CH2Cl2). The reaction was stirred until HPLC indicated completion of reaction (2 h). The reaction was diluted with EtOAc and washed with saturated aqueous NaHCO3/Na2S2O3 1:1 (3×). The aqueous layer was back extracted with EtOAc (2×). The combined organic layers were dried (Na2SO4), filtered, and evaporated to give a crude yellow solid (53 mg, 96%) that was used without further purification. 1H-NMR (DMSO-d6) δ 9.35 (s, 1H), 8.98 (s, 1H), 8.62 (d, J=7.2 Hz, 1H), 7.80 (s, 1H), 7.62 to 7.28 (m, 6H), 2.71 (t, J=7.5 Hz, 2H), 2.41 (t, J=7.4 Hz, 2H); MS [M+H]+=487; LCMS RT=2.62 min.
