Journal of Heterocyclic Chemistry, 26, p. 1589, 1989 | | Synthesis | General procedure for the synthesis of 2-chloro-3-quinolinecarboxylic acid from 2-chloro-3-quinolinecarboxaldehyde: General method: a mixed solution of 2-chloro-3-quinolinecarboxaldehyde (0.5 mmol), tert-butylhydrogen peroxide (TBHP, 4.0 eq.), and dichloroethane (DCE, 2.0 mL) was placed under aerobic environment and heated at 80°C for 6 to 8 hours. Upon completion of the reaction, the solvent was removed by distillation under reduced pressure. Water was added to the reaction mixture and extracted with ethyl acetate (EtOAc). The organic phase was washed sequentially with water and saturated saline and subsequently dried over anhydrous sodium sulfate (Na2SO4). The organic solvent was removed by concentration under reduced pressure, and the resulting crude product was purified by column chromatography (eluent ratio: hexane:ethyl acetate=15:5) to afford the target product 2-chloro-3-quinolinecarboxylic acid. | | References | [1] Tetrahedron Letters, 2018, vol. 59, # 11, p. 1019 - 1022
