Reaction Steps
To a solution of 3.26 ml of ethyl acetoacetate in ethanol (20 ml) is added dropwise 0.5 ml of a sodium ethoxide solution (21% in EtOH) at 0° C. The mixture is stirred for 15 minutes and 5.82 g de 2-bromo-1-(2,4-dichlorophenyl)ethanone predissolved in 30 ml of an ethanol/toluene mixture (2/1; v/v) is then added. The mixture is stirred for 4 hours at RT and then concentrated to dryness. The residue is purified by chromatography on silica gel to give 3.8 g of liquid corresponding to the expected product.
