Ethyl formate → Ethyl 2-(benzyloxy)-3-oxopropanoate

関与物質

反応手順

To a suspension of sodium hydride (3.3 g, 60% in paraffin oil, 82.5 mmol) in dry ether (100 mL) and dry ethyl formate (5.55 g, 75 mmol) was added ethyl(benzyloxy)acetate (14.57 g, 75 mmol) dropwise with stirring. The resulting mixture solution was then refluxed for 2 h and concentrated to give crude ethyl 2-(benzyloxy)-3-oxopropanoate which was used in the subsequent step without further purification.
