In tetrahydrofuran (225 ml) was dissolved 15 g of 3-nitrophenethyl alcohol, followed by adding triphenylphosphine (26 g) and phthalimide (13.9 g). Then, the resulting mixture was ice-cooled, followed by dropwise addition of diethyl azodicarboxylate (15.5 ml). After stirring at room temperature for 1 hour, the resulting crystals were collected by filtration, washed with diethyl ether and dried, to give N-(3-nitrophenethyl)phthalimide as colorless crystals.
