| titleOfInvention | Method for producing esters |
| abstract | PROBLEM TO BE SOLVED: To produce an ester having a maleimide group efficiently and industrially by a simple operation using a reagent that is industrially easy to use, and without any by-product contamination. Become. The following general formula (I) (In the formula, R represents a divalent hydrocarbon group which may have a substituent, and part of the skeleton of the hydrocarbon group may be substituted with an oxygen atom). A maleic amino acid and a hydroxy compound having an imide ring skeleton are reacted in the presence of a carbodiimide-based condensing agent to perform esterification and intramolecular cyclization of the compound represented by the above general formula (I). A method for producing an ester having a maleimide group, wherein the ester having a maleimide group is crystallized by contacting with water. [Selection figure] None |
