1-Chloro-4-(chloromethyl)benzene → 4-(2-Fluoroethoxy)benzyl 4-chlorobenzyl ether

Participants

Reaction Conditions

Reaction Steps

A mixture consisting of 5.3 g of 4-(2-fluoroethoxy)benzyl alcohol, 5.0 g of 4-chlorobenzyl chloride, 0.5 g of triethylbenzylammonium bromide and 20 g of a 50% aqueous solution of sodium hydroxide was stirred at 50° C. for 4 hours. The reaction mixture was cooled to room temperature, poured into water, and extracted with toluene. The toluene layer was washed with water, and dried over anhydrous sodium sulfate. Toluene was evaporated under reduced pressure. The resulting crude ether was purified by silica gel (200 g) column chromatography (developing solvent: benzene) to give 8.2 g of the desired 4-(2-fluoroethoxy)benzyl 4-chlorobenzyl ether as pale yellow crystals.
