実験手順

A mixture of 4-(2-methyl-5-(pyridin-4-yl)-2H-1,2,3-triazol-4-yl)phenol (80 mg, 0.32 mmol), 2-(chloromethyl)quinoline hydrochloride (71 mg, 0.33 mg), and cesium carbonate (414 mg, 1.27 mmol) in dimethylformamide was heated at 65° C. for 20 h, filtered, the filtrate concentrated and chromatographed on silica eluted with ethyl acetate-hexanes providing material containing starting phenol. This was dissolved in ethyl acetate, washed with aqueous NaOH, dried and concentrated giving a colorless solid (100 mg, 80%). 1H NMR (CDCl3, 400 mHz) δ 8.56 (d, 2H, J=6.2 Hz), 8.24 (d,1H, J=8.3 Hz), 8.12 (d, 1H, J=8.3 Hz), 7.85 (d, 1H, J=8.3 Hz), 7.75 (ddd, 1H, J=8.5, 7, 1.6 Hz), 7.70 (d, 1H, J=8.7 Hz), 7.65 (d, 2H, J=6.2 Hz), 7.57 (m, 1H), 7.41 (m, 2H), 7.08 (m, 2H), 5.45 (s, 2H), 4.27 (s, 3H). MS (AP+) m/e 394 (MH+).
