75% | With acetic anhydride; at 150℃; for 30h; | General procedure: A mixture of 2-methylquinoline (5a, 0.14 g, 1 mmol), <strong>[92-55-7](5-nitrofuran-2-yl)methylene diacetate</strong> (0.72 g, 3 mmol) and acetic anhydride (30 mL) was heated at 150 C for 30 h (TLC monitoring). After cooling, the solvent was removed in vacuo to provide the crude product, which was purified by flash column chromatography (FC, silica gel use CH2Cl2 as eluent) to give 6a (0.22 g, 81%) as a yellow solid. |

68% | With toluene-4-sulfonamide; In toluene; at 120℃; for 12h;Inert atmosphere; | A solution of 6-fluoro-2-methylquinoline (200 mg, 1.24 mmol), p-toluenesulfonamide (212 mg, 1.24 mmol) and pyrazine-2-carbaldehyde (134 mg, 1.24 mmol) in toluene (4 mL) was refluxed at 120° C. for 12 h in a reaction tube under N2. After the mixture was cooled to room temperature, the solvent was removed under reduced pressure. Then the concentrate was purified by column chromatography with EtOAc/Hexane (1:4, v/v) on silica gel, affording TZ-36-22 as a light yellow solid (211 mg, 68percent). 1H NMR (400 MHz, DMSO-d6) delta 8.93 (d, J=1.4 Hz, 1H), 8.67 (dd, J=2.4, 1.5 Hz, 1H), 8.55 (d, J=2.5 Hz, 1H), 8.38 (d, J=8.6 Hz, 1H), 8.07 (dd, J=9.3, 5.5 Hz, 1H), 7.93 (dd, J=15.5, 6.2 Hz, 3H), 7.77 (dd, J=9.4, 2.9 Hz, 1H), 7.66 (td, J=8.9, 2.9 Hz, 1H). |
