Reaction Steps
To a solution of 2.50 g of methyl 2-(3-methoxybenzyl)-tetrahydro-2-furancarboxylate in 50 ml of dichloromethane was added 22 ml of a 1 M solution of boron tribromide in dichloromethane at −70° C. under an atmosphere of nitrogen gas. After warming to 0° C., the mixture was cooled again to −70° C., and 20 ml of methanol was added. 200 ml of dichloromethane and 100 ml of water were further added. The organic layer was dried over anhydrous magnesium sulfate, and the solvent was evaporated, to give 2.20 g of the title compound.
