実験手順: 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. cooling evaporated in vacuo The residue was purified by chromatography on silica gel

実験手順: To a suspension of lithium aluminum hydride (4.05 g) in tetrahydrofuran (475 ml) was added dropwise a solution of 4-octyloxybenzaldehyde (25 g) in tetrahydrofuran (25 ml) at 55°-60° C. The reaction mixture was stirred under reflux for 1 hour. Thereto, sodium fluoride (35.84 g) and water (11.52 ml) were added under ice-cooling. The mixture was stirred for 30 minutes, and filtered. The filtrate was evaporated in vacuo to give 4-octyloxybenzyl alcohol (25.1 g) as crystals. under reflux for 1 hour cooling The mixture was stirred for 30 minutes filtered The filtrate was evaporated in vacuo
