Abstract
PURPOSE: In the condensation reaction of ethyl acetoacetate, ethanol is combined at the beginning of the reaction, thus producing title compound in high yield.
CONSTITUTION: In the producting of ethyl isodehydroacetate by condensation reaction of ethyl acetoacetate in the presence of hydrogen chloride, ethanol is combined from the beginning of the reaction. Although ethanol is formed by the reaction, the previous addition raises the maximum yield of the product, though it somewhat retards the reaction rate.
