Pyridine → 4-(4-Fluorophenoxy)benzylchloride

Participants

Reaction Steps

To the solution of (4-(4-fluorophenoxyl)phenyl)methanol (7 g, 32.1 mmol) and pyridine (5.19 mL, 64.2 mmol) in dichloromethane (DCM) (100 mL) was added sulfurous dichloride (7.63 g, 64.2 mmol) dropwise at 0° C. After addition the mixture was stirred at room temperature overnight. The mixture was washed with saturated NaHCO3 solution (40 mL×2) and brine (40 mL), the organic phase was dried over Na2SO4, filtered and concentrated to leave the crude product, which was purified by column chromatography (silica-gel, elution with PE: EtOAc=6:1) to afford the pure 1-(chloromethyl)-4-(4-fluorophenoxyl)benzene (2.2 g, 8.83 mmol, 27.5% yield) as light yellow oil. LCMS: rt=1.56 min, [M+H+]=237
