Description
本発明は、フォンダパリヌクスナトリウムを調製するための方法を提供する。この本明細書に記載の新規な方法により、フォンダパリヌクスナトリウムをより高い収率かつより少ない不純物で得られる。本発明の方法は、特定の合成工程に必要な時間を減ずることにより製造コストを低減させる。
本明細書で使用する用語「接触」とは、少なくとも2つの異なる種同士が反応できるように接触させるプロセスを指す。しかし、得られる反応生成物は、添加試薬同士の反応から直接的に生じてもよく、あるいは反応混合物中で生じる添加試薬の1つまたは複数由来の中間体からも生じてもよいことが、理解されるべきである。
本明細書に記載する方法における出発材料ABCDE4は、以下のような一連の工程により調製される。まず、ABC1を、以下の工程(a)および(b)により調製する。
a)式A4:
b)式ABC1:
