Procedure
To a solution of 4-(1-hydroxypropyl)-6-iodo-3-methyl-1-prop-2-ynyl-1H-pyridin-2-one 4b (44 mg, 0.13 mmol) and 4-dimethylaminopyridine (2 mg, 1.2 μmol) in CH2Cl2 (2 mL) was added NEt3 (53 mg, 74 μL, 0.52 mmol) and bromodiisopropyl(3, 3, 4, 4, 5, 5, 6, 6, 6-nonafluorohexyl)silane (147 mg, 0.33 mmol, prepared by mixing diisopropyl-(3, 3, 4, 4, 5, 5, 6, 6, 6-nonafluorohexyl)silane and Br2) and the mixture was stirred for 12 h. The solvent was evaporated and the residue was purified by flash chromatography (hexanes-EtOAc 15:1) to afford 5b (75 mg, 82%) as a colorless oil: 1H NMR (300 MHz, CDCl3) δ6.99 (s, 1H), 5.12 (d, J=16.5, 1H), 5.00 (d, J=16.5, 1H), 4.75 (t, J=6.0 Hz, 1H), 2.33-2.31 (m, 1H), 2.07-1.99 (m, 2H) 2.06 (s, 3H), 1.84-1.60 (m, 2H), 1.00 (s, 14H), 0.88 (t, J=7.4 Hz, 3H), 0.83-0.79 (m, 2H); 13C NMR (75 MHz, CDCl3) δ162.4, 152.5, 123.7, 118.6, 94.2, 72.8, 71.5, 44.3, 31.1, 25.3, 17.5, 12.6, 9.4, 0.3.
