Abstract
【解決手段】溶媒としての少なくとも1種の(C2−C3)アルカノール中において2−(2−ニトロベンジリデン)アセト酢酸メチルを、3−アミノクロトン酸メチルと反応させることを含んでなり、該反応を加圧下に70〜110℃の温度で行うことを特徴とするニフェジピンの製造法。好ましくは75〜95℃の温度、特に好ましくは約85℃においてメタノール中で反応を行う。
【選択図】なし
Description
そのような精製操作には収率の損失が伴い、純粋なニフェジピンの収率は合成法の収率より有意に低い。
な化合物として用いるために要求される純度を示さない。かくして、HPLC分析手段により、パーセントの範囲の原子価異性体(valeuce isomer)(II)の存在を検出することができ、その除去/転位は追加の純粋な結晶化を必要なものとする。その場合の収率は理論値のわずか70〜75%である。
本発明はこれらの発見に基づいて完成されたものである。
薬学的に活性な化合物の合成において通常行われる濾過を行うことができ、それは示した温度範囲において加圧下で反応させることのさらなる利点を与える。
1185g(4.76モル)の2−(2−ニトロベンジリデン)アセト酢酸メチルを密閉された撹拌容器において、600g(5.22モル)の3−アミノクロトン酸メチルと一緒に1900mlのメタノール中で85℃に加熱し、85℃で10時間撹拌する。次いで混合物を40℃に冷却する。結晶を吸引濾過し、メタノール及び水で洗浄する。真空中で乾燥した後、1400g(=理論値の85%)のニフェジピンが得られる。
