Sodium hydride → 1-Bromo-4-methoxy-2-(methoxymethoxy)benzene

Participants

Reaction Steps

To a suspension of NaH (2.5 g, 0.06 mol) in dry DMF (100 mL) at 0° C. was added solution of 1-bromo-2-hydroxy-4-methoxybenzene (10.6 g, 0.05 mol). After stirring at 0° C. for 30 min. bromomethyl methyl ether (7.8 g, 0.06 mmol) were dropwise added. The mixture was warmed to room temperature over 20 min. and then stirred for 2 h, it was then quenched cautiously by the addition of cold dilute HCl and extracted with EtOAc. The EtOAc extract was washed successively with; H2O, 5% aqueous NaHCO3, H2O and finally brine. After drying (MgSO4) filtration and evaporation gave liquid. The product was purified by distillation (85° C., 0.2 mm Hg) to give the title compound as a colorless oil (13.7 g, 97%).
