  "claims": [
    "1. The method to prepare N-(2-methyl-1-naphthyl)maleimide consisting essentially in heating equimolar amounts of 2-methyl-1-naphthylamine with maleic anhydride in the presence of lower fatty acid to a temperature between 100° C. and the boiling point of the reaction mixture for a period of 1-10 hours.",
    "2. The process of claim 1 wherein said heating is carried out in the presence of glacial acetic acid.",
    "3. The process of claim 1 wherein glacial acetic acid is used in a volume of 0.2-1.6 liters per mole of reactants.",
    "4. The method to prepare N-(2-methyl-1-naphthyl)-maleimide consisting essentially in heating equimolar amounts of 2-methyl-1-naphthylamine with maleic anhydride in the absence of a solvent to a temperature of 130°-190° C. for at least one hour."
