실험 절차

SelectFluor (2.04 g, 5.8 mmol, 2 equiv) was added to a cold (−5° C.) solution of 5-(3,5-dimethoxy-phenyl)-quinoline-8-carboxylic acid ethyl ester (Step 174.2) (970 mg, 2.9 mmol) in CH3CN (40 mL), under an argon atmosphere. The reaction mixture was allowed to warm to rt, stirred at that temperature for 6 h, quenched by addition of a saturated aqueous solution of NaHCO3, and concentrated. The residue was diluted in EtOAc and a saturated aqueous solution of NaHCO3. The aqueous phase was separated and extracted with EtOAc. The combined organic layers were washed with H2O and brine, dried (Na2SO4), filtered and concentrated. The residue was purified by silica gel column chromatography (Hex/EtOAc, 3:2) followed by trituration in Et2O to provide 355 mg of the title compound: ESI-MS: 356.2 [M+H]+; tR=3.80 min (System 1); TLC: Rf=0.18 (Hex/EtOAc, 3:2).
