Claims (6)

  1. 수성 염산을 사용하여 구조식(Ia)의 화합물 또는 이의 산부가염의 에스테르 그룹을 분해시키고, 이렇게 하여 생성된 세프타지딤을, 염기를 가하여 5수화물로서 반응 혼합물로부터 직접 결정화시키거나, 아세톤 및/또는 에탄올, 또는 다른 수-혼화성 반-용매(anti-Solvent)를 가하여 먼저 세프타지딤의 디하이드로 클로라이드를 분리시킨 다음, 이를 공지방법에 따라 5수화물로 전환시킴을 특징으로 하여, 구조식(III)의 세프타지딤의 5수화물을 제조하는 신규한 방법.
  2. 제1항에 있어서, 수성 염산의 농도가 20 내지 40중량%임을 특징으로 하는 방법.
  3. 제1항 또는 2항에 있어서, 에스테르 분해를 -15 내지 +35℃에서 수행함을 특징으로 하는 방법.
  4. 제1항 내지 3항중의 어느 한 항에 있어서, 세프타지딤의 5수화물을, 세프타지딤 디하이드로클로라이드의 중간 분리없이 반응 용액으로부터 직접 결정화시킴을 특징으로 하는 방법.
  5. 제1항 내지 제3항중의 어느 한 항에 있어서,
    아세톤 및/또는 에탄올을 가하여 반응 혼합물로부터 세프타지딤의 디하이드로크롤라이드를 결정화시키고 이를 공지방법에 따라 세프타지딤 디하이드로클로라이드를 결정화시키고 이를 공지방법에 따라 세프타지딤 5수화물로 전환시킴을 특징으로 하는 방법.
  6. 수성 염산을 사용하여, 제1항에 기술된 구조식(Ia)의 화합물 또는 이의 산부가염의 에스테르 그룹을 분해시키고 생성된 디하이드로클로라이드를 아세톤 및/또는 에탄올 또는 다른 수-혼화성 반-용매를 가하여 결정화시킴을 특징으로 하여, 세프타지딤의 디하이드로클로라이드를 제조하는 방법.
