The pyrolysis under 170–220°C or boiling in DMF of malonanilic acids ethyl esters (2) is accompanied by formation of malonic acids symmetric dianilides (7) with high yields. A possible mechanism for this transformation has been suggested.

The influence of the α-substitution on hydantoin formationfrom urethan protected alaninamide derivatives is investigated. Several 5-methyl-5-substituted hydantoins, obtained from 5-amino-5-methylhydantoin, are described.
Parmi 13 nouveaux dérivés des séries des dialcoylaminoéthylamides et des esters dialcoylaminoéthyliques des acides dialcoylmaloniques, le bis-(diéthylaminoéthylamide) et le diester diéthylaminoéthylique de l'acide diéthylmalonique se font remarquer par leurs propriétés analgésiques, tandis que l'ester diéthylaminoéthylique de l'éthylbutylmalonate monoéthylique se distingue par son action spasmolytique
