Procedure

Fluoroalkylation conditions were based on a paper by Timperley et al. J. Fluorine Chem. 2006, 127, 249. A solution of 4-[1-(5-hydroxy-pyridin-2-yl)-1H-[1,2,4]triazol-3-yl]-benzaldehyde O-((2S,3R,4R,5S,6S)-3,4,5-trimethoxy-6-methyl-tetrahydropyran-2-yl)-oxime in 10 mL anhydrous DMF/THF (1:1) under a N2 atmosphere was cooled at 0° C. while an excess of hexafluoropropylene gas was added over 15 min. Following addition, triethylamine (15 uL, 0.109 mmol) was added and the reaction mixture warmed to ambient temperature before concentration to dryness. Chromatography (EtOAc/hexanes, 1:1) afforded Compound 94 (16 mg, 24%). 1H NMR (CDCl3) δ 9.17 (s, 1H), 8.39 (d, J=7.68 Hz, 1H), 8.21 (d, J=8.22 Hz, 2H), 8.19 (s, 1H), 8.08 (d, J=7.68 Hz, 1H), 7.74 (d, J=8.22 Hz, 2H), 6.97 (s, 1H), 5.63 (d, J=1.85 Hz, 1H), 5.17 (m, 1H), 3.78 (dd, J=3.28, 1.99 Hz, 1H), 3.63 (m, 1H), 3.59 (s, 3H), 3.57 (s, 3H), 3.56 (s, 3H), 3.43 (dd, J=9.31, 3.36 Hz, 1H), 3.18 (t, J=9.48 Hz, 1H), 1.29 (d, J=6.26 Hz, 3H); EIMS 619 m/z (M+).
