Synthesis
The general procedure for synthesizing ethyl 2-phenylethylacetoacetate from ethyl acetoacetate and β-bromophenylethane is as follows: with reference to Example 3, the operation is the same as that of Reference Example 1, except that 55.5 g (300 mmol) of β-bromophenylethane, 42.9 g (330 mmol) of ethyl acetoacetate, 27.8 g of toluene, 103 g (748 mmol) of potassium carbonate, and 2.08 g of water as reactants. Upon completion of the reaction, 77.4 g of ethyl 2-phenylethyl acetoacetate crude product was obtained. The crude product was analyzed to contain 68.9 wt% of ethyl 2-phenylethylacetoacetate in 77% yield.
