To a solution of trimethylsulfoxonium iodide (59.0 mg, 0.268 mmol, 1.3 eq.) in anhydrous DMSO (1.5 mL) was added sodium hydride (5.4 mg, 0.227 mmol, 1.1 eq.) and the reaction was heated to 50° C. for 30 minutes. The reaction was then cooled to room temperature and a solution of (E)-2-(2-(6-(3,5-dimethyl-1H-1,2,4-triazol-1-yl)-2-methylpyrimidin-4-yl)vinyl)quinoline (1-4) (70.0 mg, 0.205 mmol, 1.0 eq.) in DMSO (1.5 mL) was added. The reaction was stirred at room temperature for 1 hour, poured into water (5.0 mL) and extracted using ethyl acetate (3×5.0 mL). The combined organic layers were dried over sodium sulfate, filtered and concentrated to dryness. The residue was purified by silica gel column chromatography (10-40% ethyl acetate in hexanes) to afford trans-2-(2-(6-(3,5-dimethyl-1H-1,2,4-triazol-1-yl)-2-methylpyrimidin-4-yl)cyclopropyl)quinoline (1-5) as an off-white solid. 1H NMR (300 MHz, CDCl3) δ 8.03 (br d, 1H, J=8.5 Hz), 7.98 (br d, 1H, J=8.4 Hz), 7.75 (br dd, 1H, J=8.0, 1.0 Hz), 7.67 (ddd, 1H, J=8.5, 7.0, 1.5 Hz), 7.60 (br s, 1H), 7.46 (ddd, 1H, J=8.0, 7.0, 1.0 Hz), 7.33 (d, 1H, J=8.5 Hz), 2.96-2.83 (m, 2H), 2.89 (s, 3H), 2.68 (s, 3H), 2.06-1.94 (m, 2H). LRMS m/z (M+H+) 357 found, 357 required. m.p. 140-141° C.
