Sodium Iodide → 5-Chloro-2-(2,3-difluoro-6-methoxybenzyloxy)anisole

Participants

Reaction Conditions

Reaction Steps

A mixture of 2,3-difluoro-6-methoxybenzyl chloride (7.65 g), 4-chloro-2-methoxyphenol (6.34 g), potassium carbonate (8.29 g) and sodium iodide (1.2 g) in N,N-dimethylformamide (20 mL) was stirred at 80° C. for 2 hours. The reaction mixture was poured into water, and the resulting mixture was extracted with diethyl ether. The extract was washed with 1 mol/L aqueous sodium hydroxide solution, water and brine successively, and dried over anhydrous magnesium sulfate, and the solvent was removed under reduced pressure. The residual solids were suspended in a mixed solvent (n-hexane/diethyl ether=5/1), and collected by filtration. The collected solids were washed with the same solvent, and dried under reduced pressure to give the title compound (8.6 g).
