YieldReaction ConditionsOperation in experiment
7%; 3% With caesium carbonate; In acetonitrile; at 80℃; for 2h; Compound 42 (104 mg, 1.06 mmol) and cesium carbonate (346 mg, 1.06 mmol) were suspended in anhydrous acetonitrile (2 mL). Compound 12 (266 mg, 1.06 mmol) was dissolved in 2 mL of anhydrous acetonitrile and added dropwise to above suspension. The reaction was then continued 80 C for 2 h. The solvent was removed evaporated and the resulting crude was purified by column chromatography on silica gel using gradient 0-3% methanol in dichloromethane to give products 49 (19 mg, 7%) and 50 (8 mg, 3%) as white solids. Compound 49: mp 186-188 C, 1H NMR (CDCl3) δ 2.23 (s, 3H), 2.34 (s, 3H), 5.11 (s, 2H), 5.52 (s, 1H), 6.37 (s, 1H), 7.30-7.36 (m, 1H), 7.42 (t, J = 7.91 Hz, 2H), 7.55 (d, J = 7.53 Hz, 2H); MS ESI (+ve) for C15H16N4O (M+H+): calcd 269.14; found: 263.23. Compound 50: 1H NMR (CDCl3) δ 1.92 (s, 3H), 2.28 (s, 3H), 5.00 (s, 2H), 5.40 (s, 1H), 5.97 (s, 1H), 7.32-7.58 (m, 5H); MS ESI (+ve) for C15H16N4O (M+H+): calcd 269.14, found: 269.23.
