<p>A process for producing butyric ester derivatives of general formula (2) in high yields, wherein compounds of general formula (1): HOCH2-CH=CH-COOR can be efficiently removed. This process for producing butyric ester derivatives of general formula (2) comprises treating a butyric ester derivative of general formula (2) containing a compound of general formula (1) with an addition reagent capable of adding itself to the ethylene bond to form an adduct separable from the butyric ester derivative of general formula (2), or reacting a compound of general formula (3) with a cyanide by the flow method.</p> |
