  • 2,6-dioxopiperidine derivatives, their preparation and pharmaceutical compositions containing them
    Patent number: 5071857
    Abstract: In the treatment of oestrogen-dependent tumors, it is desirable to improve the therapy obtainable from the compound aminoglutethimide. It has now been found that 3-ethyl-3-(4-pyridyl)glutarimide and derivatives thereof of formula ##STR1## wherein R represents a hydrogen atom or an alkyl group having 1 to 4 carbon atoms offers advantages over aminoglutethimide. 3-Ethyl-3-(4-pyridyl)glutarimide can be prepared by various ring-closing reactions, especially by heating 4-(4-pyridyl)-hexano-1,4-dinitrile with a strong mineral acid.
