An improved process for producing piperidine-2,6-diones heterocyclically substituted at the 3-position in a minimal number of reaction stages by reacting a 2-aminobenzylamine with a 3-bromoglutarimide to obtain an amine of formula (IV):
and thereafter reacting the obtained amine of formula (IV) with a suitable further reactant.
一种改进的方法,用最少的反应步骤产生在3位杂环取代的
哌啶-2,6-二酮,方法是将2-
氨基苯
甲胺与3-
溴戊二
酰亚胺反应,得到化合物(IV)的胺,然后将得到的化合物(IV)的胺与适当的进一步反应物反应。
