N-[4-(2-fluoroethoxy)phenyl]acetamide → HCID 15058655, compound

Participants

Reaction Steps

A solution of 3.0 grams (0.015 mole) of 4-acetamidophenyl 2-fluoroethyl ether in 15 ml of dry tetrahydrofuran was added dropwise to a stirred solution of 15 ml of a 3.4 M solution of sodium bis(2-methoxyethoxy)aluminium hydride (Red-Al®) in toluene and 50 ml of dry tetrahydrofuran. The reaction mixture was stirred at room temperature for approximately 18 hours. The mixture was quenched with 1 ml of water and was filtered. The filtrate was evaporated under reduced pressure leaving a dark liquid which solidified upon standing. This solid was dissolved in ethyl acetate to which a small amount of water was added. A small amount of precipitate formed from which the organic solution was decanted. The organic solution was evaporated under reduced pressure leaving a dark liquid residue. This residue was purified by column chromatography on silica gel followed by distillation under reduced pressure to yield 1.6 grams of 4-(ethylamino)phenyl 2-fluoroethyl ether as a solid.
