    Abstract: PROBLEM TO BE SOLVED: To provide a method for synthesizing dicarboxylic acid imide in solution.
    SOLUTION: This method for producing the dicarboxylic acid imide expressed by general formula (I); R
    1 -(CO)-(NR
    3 )-(CO)-R
    2 , is provided by reacting a dicarboxylic acid anhydride expressed by general formula (II): R
    1 -(CO)-O-(CO)-R
    2 , with urea or a urea derivative expressed by formula: (R
    3 HN)-(CO)-(NR
    3 H) in the solvent. The method can be used for the production of especially a thalidomide.
