Procedure

To a stirred solution of 4′-(2-hydroxyethyl)-2,2,2-trifluoroacetanilide (5.9 g) in tetrahydrofuran (20 ml) and dichloromethane (20 ml) were added N,N-diisopropylethylamine (5.7 ml) and benzyl chloromethyl ether (3.9 ml) under ice-cooling, and the mixture was stirred for 24 hours at room temperature. The reaction mixture was poured into ice-water and extracted with ethyl acetate. The extract was washed with brine and dried over anhydrous magnesium sulfate. Removal of the solvent under reduced pressure gave 4′-[2-(benzyloxymethoxy)ethyl]-2,2,2-trifluoroacetanilide (9.7 g).
