YieldReaction ConditionsOperation in experiment
90% With hydrogen bromide In water at 105℃; for 88.5 h; Step E.
7-Hydroxyquinoline-3-carboxylic acid.
Ethyl 7-methoxyquinoline-3-carboxylate (7.03 g, 30.4 mmol) was dissolved in HBr (48percent aq., 150 mL) and was heated at 105° C. for 88.5 h.
The reaction was cooled to ambient temperature and the precipitate was collected by filtration to afford the title compound as a brown solid (5.2 g, 90percent).
1H NMR (400 MHz, DMSO-d6) δ 12.05-11.67 (m, 1H), 9.49 (d, J=2.0 Hz, 1H), 9.43 (s, 1H), 8.39 (d, J=9.8 Hz, 1H), 7.55-7.51 (m, 2H).
[M+H]=190.2.
