PROBLEM TO BE SOLVED: To provide a simple manufacturing method of an alkali metal salt of a cyanoketone containing a small amount of an alkali metal carboxylate from a carboxylate ester and acetonitrile. SOLUTION: A carboxylate ester represented by general formula (1) (wherein R<SP>1</SP>and R<SP>2</SP>are the same or different and are each a 1-6C alkyl group or a 3-8C cycloalkyl group) is caused to react with acetonitrile in the presence of a base containing an alkali metal and subsequently methanol is added to the reaction mixture to give the alkali metal salt of the cyanoketone represented by general formula (2) (wherein R<SP>1</SP>is the same as defined above; and M is an alkali metal atom).
