5-Phenylpentan-1-ol (0.50 g, 3 mmol), triphenylphosphine (0.45 g, 3 mmol), and phthalimide (0.80 g, 3 mmol) were vigorously stirred in dry THE (5 mL) while cooling to 0° C. A solution of DEAD (0.62 g, 3 mmol) in 5 mL of dry THF was added dropwise to the cooled mixture. After stirring at room temperature for 12 his, the solvent was removed by reduced pressure. The crude was purified by column chromatography using a Teledyne ISCO apparatus (cyclohexane:EtOAc 90:10) to afford the title compound (0.68 g, 76%) as a white solid. 1H NMR (400 MHz, DMSO-d6): δ 1.22-1.34 (m, 2H), 1.49-1.69 (m, 4H), 2.52-2.58 (m, 2H), 3.56 (t, J=7.06 Hz, 2H), 7.06-7.27 (m, 5H), 7.75-7.95 (m, 4H). MS (ESI) m/z: 334 [M-H]−.
