Reaction Steps

A mixture of N-(2-hydroxyethyl)phthalimide (3.59 g, 18.75 mmol), 4-hydroxybenzotrifluoride (3.04 g, 18.75 mmol), diethyl azodicarboxylate (4.37 ml, 28.13 mmol) and triphenylphosphine (7.38 g, 28.13 mmol) in THF (50 ml) was stirred at room temperature overnight. The reaction mixture was concentrated under reduced pressure, and the residue was purified by silica gel column chromatography (n-hexane/ethyl acetate=5/1) to afford N-[2-(4-trifluoromethylphenoxy)ethyl]phthalimide (4.05 g, yield 69%) as a colorless crystalline powder.
