Diethyl azodicarboxylate (18.4 g) was added dropwise to a suspension of 4-octyloxybenzyl alcohol (25 g), N-hydroxyphthalimide (17.15 g) and triphenylphosphine (27.74 g) in tetrahydrofuran (250 ml) under ice-cooling. The reaction mixture was stirred at room temperature for 2 hours, and evaporated in vacuo. The residue was purified by chromatography on silica gel to give N-(4-octyloxybenzyloxy)phthalimide (33.45 g) as crystals.
