Water → Allyl benzyl ether

참여 물질

반응 단계

To a solution of isomer A product from Step 1 (1.62 g, 4.23 mmol) in THF (50 mL) was added NaH 60% (540 mg, 13.4 mmol) followed by benzylbromide (1.5 mL, 13.4 mmol) and the reaction was stirred at 55 C overnight. The cooled mixture was poured into water, extracted with EtOAc, dried over Na2SO4 and concentrated. The residue was purified by flash-chromatography over silica gel (eluted with Hexanes/AcOEt 99:1 to 50:50) to afford 1.07 g (53%) of allylbenzylether isomer A.
