QUINOLON-NAPHTHYLIDONE CARBOXYLIC ACID, AND ESTER PRODUCTION METHOD THEREOF

摘要

PURPOSE: A quinolon naphthylidone carboxylic acid and a production method of ester that starts from benzoil chloride and nicotinoil chloride is provided. CONSTITUTION: A production method of ester has the steps of: reacting the benzoil chloride or nicotinoil chloride with ester aminiacrylic acid to obtain ester acryloid acrylic acid; amine-exchanging the ester acryloid acrylic acid with amine to obtain (Het)-acryloid acrylic acid; looping the ester acryloid acrylic acid to obtain ester naphthylidone.
