実験手順

To a solution of 3-(4-bromo-2-(diethylcarbamoyl)phenoxy)-2-fluoropyridine 1-oxide (420 mg, 1.096 mmol) in 15 mL of DCM was added dropwise phosphorus oxychloride (301 μl, 3.29 mmol) followed by 2 drops of DMF. After stirring at rt for 1 h, the reaction was quenched with sat. NaHCO3, extracted into EtOAc, dried over Na2SO4, filtered and concentrated under reduced pressure. The crude was purified by column chromatography (DCM to DCM/EtOAc gradient beginning from 10:1 to 5:1 to 3:1) gave 5-bromo-2-(6-chloro-2-fluoropyridin-3-yloxy)-N,N-diethylbenzamide as a colorless gum.
