Ethyl (2-Furoyl) Acetate (Ethyl α-Oxo-2-Furanpropionate)
A 300-ml four-necked round-bottomed flask fitted with mercury-sealed stirrer, dropping funnel, and reflux condenser protected by a calcium chloride tube was charged with 24.8 g (0.177 mole) of freshly distilled ethyl 2-furoate, m.p. 33–34°. The stirrer was set in motion, and the flask was heated in a water bath at a bath temperature of 75–80°. At this temperature 2 g of sodium wire was added (Note 1), and 8.8 g (9.8 ml) of ethyl acetate was added gradually from the dropping funnel (Note 2).
