Thionyl Chloride → HCID 59527509, compound

Participants

Reaction Steps

[4-(Benzyloxy)-6-fluoro-3-methylquinolin-2-yl]methanol (4.02 g) was dissolved in THF (50 mL) and toluene (50 mL), and 10 drops of pyridine were added thereto. Thionyl chloride (1.50 mL) was gradually added dropwise thereto under ice-cooling, and the reaction mixture was stirred at the same temperature for 1 hour, and further stirred at room temperature for 1 hour. After the precipitated solid was collected by filtration, ethyl acetate and a saturated aqueous sodium hydrogen carbonate solution were gradually added with stirring to the filtrate under ice-cooling. After the foaming became stable, the organic layer was separated, washed sequentially with water and saturated brine and dried over anhydrous magnesium sulfate. The solvent was evaporated. The residue was purified by silica gel column chromatography (eluent: chloroform) to obtain 4-(benzyloxy)-2-(chloromethyl)-6-fluoro-3-methylquinoline (3.85 g).
