실험 절차
To a stirred solution of 2-chloro-6-methoxyquinoline-3-carbaldehyde (5.27 g, 23.8 mmol) in anhydrous CH2Cl2 (180 mL) in a 500 mL round-bottomed flask equipped with a magnetic stirrer was added dropwise BBr3 (71.3 mL, 71.3 mmol) at 0° C. and the mixture was stirred at RT overnight. The mixture was then added dropwise to a water/ice mixture, and the solid was filtered and dried under vacuum to give 2-chloro-6-hydroxyquinoline-3-carbaldehyde SLA 47016 as a yellow solid (3.14 g, 64% yield).
