1,4-Dibromobutane → Ethyl 2-(4-bromobutoxy)acetate

Participants

Reaction Steps

To a solution of sodium hydride in 40 mL DMF stirred at 0° C. was slowly added ethyl glycolate (5 g, 48 mmol). After 1 hour, 1,4-dibromobutane (8.6 mL, 72 mmol) was added, and the mixture was stirred for an additional 2 hours. The reaction was allowed to warm to room temperature for an additional 3 hours. A sodium bicarbonate solution was added, and the organic layer was dried over anhydrous sodium sulfate, concentrated and the residue was purified by chromatography to afford a colorless oil.
