Reaction Steps

Ethyl-2-(4,5-dihydrofuran-3-yl)-2-oxoacetate (45 g) was dissolved in tetrahydrofuran (225 ml) and Methanol (45 ml). The reaction mass was cooled to −5 to 0° C. N-bromosuccinimide (47 g) was added lot wise by maintaining temp below 0° C. Reaction mass was then stirred at 20-25° C. for 12 hrs. Reaction mass was concentrated to residue under vacuum at 40° C. Residue was dissolved in Ethyl acetate (450 ml) and washed with sodium sulphite solution (10%, 2×135 ml). Reaction mass was then concentrated to residue to get ethyl-2-(3-bromo-2-methoxytetrahydrofuran-3-yl)-2-oxoacetate (Yield 63 g).
