반응 단계
A solution of 5-bromo-2-hydroxybenzylalcohol (3.677 g, 18.11 mmol) in abs. EtOH (80 ml) and NaOH (0.797 g, 19.921 mmol) was stirred under a N2 atmosphere for 20 min at RT then a solution of benzylbromide (2.15 ml, 18.11 mmol) in abs. EtOH (10 ml) was added and the mixture was stirred at RT overnight. The volatiles was removed under vacuum. The reminder was partitioned between HCl (2M aq.) and EtOAc. The organic layer was washed with brine, dried (MgSO4) and evaporated to dryness. The residue was purified by MPLC (50 g SiO2 cartridge, eluent 90% iso-hexane-10% EtOAc) yielding 4.36 g of (2-benzyloxy-5-bromo-phenyl)-methanol.
