실험 절차
To 4-benzyloxybenzyl alcohol (8.1 g, 37.8 mmol) in dichloromethane (160 mL) was added N-bromosuccinimide (7.4 g, 41.6 mmol) followed by portionwise addition of triphenylphosphine (10.9 g, 41.6 mmol). The reaction mixture was stirred at room temperature for 5 minutes, and was then concentrated in vacuo. Purification by flash chromatography, eluting with 80:20 hexanes/ethyl acetate, provided 9.7 g (92%) of 1 as a white solid.
