90% | With acetic acid; for 10h;Heating; | A stirred solution of 2 (1g, 4.51 mmol) in AcOH (90 mL) was heated to 95 oC for 10 h.The reaction mixture was poured into crushed ice and stirred for 30 min. The resultingsolid was filtered, washed with water, and dried to afford 7-methoxy-2-oxo-1,2-dihydroquinoline-3-carbaldehyde (3) (0.80 g, 90%). |
76% | With acetic acid; at 110℃; for 16h; | A suspension of 2-chloro-7-methoxyquinoline-3-carbaldehyde (8.Og, 36.2 mmol) in 70% acetic acid (370 mL) was heated to 110 C for 16h. Upon cooling the reaction mixture to roomtemperature and poured into crushed ice ;solid was filtered off and washed with water, dried under reduced pressure for overnight to give title compound as pale yellow solid (5.6 g, 76%).1H NMR (400 MHz, DMSO-d6) oe 12.07 (s, 1H), 10.18 (s, 1H), 8.43 (s, 1H), 7.84 (d, J=8.9 Hz, 1H), 6.89 (dd, J=2.5 Hz, 8.8 Hz, 1H), 6.82 (d, J=1.9 Hz, 1H), 3.86 (s, 3H); LC-MS: mz 204.1 (M+1). |
