Ethyl Acetoacetate → HCID 19599015, compound

Participants

Reaction Steps

Ethyl acetoacetate (27.61 g, 0.21 mol) was dissolved in ethanol (100 ml) which was cooled in an ice-water bath, and sodium ethoxide (15.59 g, 0.22 mol) was added. 4-Vinylbenzyl chloride (33.92 g, 0.2 mole) was added. The mixture was refluxed for 16 hours, then the resulting slurry was filtered to remove any salt, and the solution collected. The solvent was removed under reduced pressure to give ethyl 2-(4-vinylbenzyl)-3-oxobutanoate in the form of a light red liquid (49 g) in 95% yield.
