The invention disclosed herein relates to a novel process for preparing the monomer, 3-[N-(3-chloropropyl)methylamino]-N,N,N-trimethyl-propan-1-aminium chlorid e, which comprises reacting N,N-bis(3-chloropropyl)methylamine with trimethylamine. The 3,3-ionene monomer thus obtained is a key intermediate for making the linear, unbranched, non-cross-linked polymer, poly-[methyl-(3-trimethylammoniopropyl)imino}trimethylene dichloride], which is valuable as an oral bile acid sequestrant.
本发明涉及一种制备单体3-[N-(3-氯丙基)甲基氨基]-N,N,N-三甲基丙基-1-铵盐的新工艺,其中包括将N,N-双(3-氯丙基)甲基胺与三甲胺反应。因此得到的3,3-离子单体是制备线性、非支链、非交联聚合物聚-[甲基-(3-三甲基胺基丙基)亚胺}三亚甲基二氯化物]的关键中间体,该聚合物作为口服胆酸吸附剂具有重要价值。
