Benzyl Bromide → 3-Benzyloxy-2-methyl-4-pyrone

Participants

Reaction Steps

11.5 g of sodium were dissolved in 300 ml CH3OH and 63g of maltol were added and stirred at room temperature for one hour. 200 ml CH3OH were added and then 102 g benzylbromide were dropped in (30 minutes). Refluxing for 3 hours and distilling off the CH3OH then yielded a residue which was dissolved in 300 ml H2O/300 ml ethyl acetate. The organic phase was washed with water and evaporated. The remaining oil was distilled in vacuo. B.P. (43 mm) =148°-150° C., 81.5 g colorless oil of the title compound was isolated.
