发明名称 Method of preparing substituted malonic ester anilides and malonic acid mono-anilides
摘要 Malonic mono-ester mono-anilides and malonic acid mono-anilides and bis-anilides are produced by reaction of malonic acid di-alkyl esters with an aniline in the presence of a stoichiometric amount, based on the aniline, of an alkali alcoholate, accompanied by the initial formation of alkali salts of mono-ester mono-anilides or malonic-acid bis-anilides. Neutralization results in the formation of free malonic mono-ester mono-anilide or malonic-acid bis-anilide and saponification forms the malonic acid mono-anilide. Chloro-substituted anilides of cyclopropyl-1,1-dicarboxylic acid and their mono-esters are preferred.
