4-Methoxybenzyl alcohol → HCID 18545246, compound

Participants

Reaction Steps

To a mixture of 5.8 ml of p-methoxybenzyl alcohol and 90 ml of N-methylpyrrolidone was added 2.13 g of sodium hydride (60% oil dispersion), and the resulting mixture was stirred at room temperature for 45 minutes in a nitrogen atmosphere. To the reaction mixture was added 9.3 g of 1-bromo-3-chloro-5-fluorobenzene, followed by stirring at 50° C. for 3 hours. The reaction mixture was poured into 50 ml of ice-diluted hydrochloric acid and extracted three times with diethyl ether-hexane (1:1 by volume). The organic layer was washed with a saturated sodium chloride aqueous solution and dried over anhydrous sodium sulfate. The solvent was evaporated, and the residue was purified by silica gel column chromatography using a hexane-ethyl acetate (19:1 by volume) mixed solvent. The fraction containing the desired compound was concentrated to furnish 13.2 g of the title compound.
