Abstract
【化1】
Description
(b)該湿ったナトリウム塩を酢酸エチル中に溶解することと;
(c)酢酸カルシウムを添加し、続いて撹拌することと;
(d)有機層を回収し、濃縮して残渣を得ることと;
(e)該残渣を乾燥して、式Iの非晶質化合物を得ること
を含んでなるものである。
1.ホウ酸エステルの脱保護、tert-ブチルエステルの開裂、およびカルシウム塩の形成が、一つの容器の中で容易に行われる;
2.安価な酢酸カルシウムを含む簡単な方法;
3.安価な方法;
4.該方法は工業的に規模を拡大することが可能;
5.非晶質アトルバスタチンカルシウムが、粗製物質を単離することなく直接得られる。
(6-{2-[2-(4-フルオロ-フェニル)-5-イソプロピル-3-フェニル-4-フェニルカルバモイル-ピロリジン-1-イル]-エチル}-2-フェニル- [1,3,2] ジオキサボリナン-4-イル)-酢酸tert-ブチルエステル(式IIの化合物、500 g、0.7 mol)を、THF(4 L)の中に溶解し、窒素ガスを用いて30分間脱ガスした。水(3.57 L)中の水酸化ナトリウム(142 g)の溶液を、上記の溶液に添加し、2時間還流させた。この反応混合物を真空下で濃縮して溶媒を除去し、水(7.5 L)を添加した後、続いてMTBE(2.5L)を加えた。層を分離した後、水溶液を真空下に1時間維持し、該溶液を12時間室温で放置した。形成された沈殿(アトルバスタチンのナトリウム塩)を濾過し、酢酸エチル(3.5 L)の中に溶解させた。この透明な有機層に、水(2 L)中の酢酸カルシウム(99.4 g)の溶液を添加し、40〜45℃で撹拌した。層を分離し、有機層を水(5×5L)で洗浄した。有機層を蒸発させ、残渣を真空下で乾燥して、非晶質のアトルバスタチンカルシウムを得た。
実施例II
(6-{2-[2-(4-フルオロ-フェニル)-5-イソプロピル-3-フェニル-4-フェニルカルバモイル-ピロリジン-1-イル]-エチル}-2-フェニル-[1,3,2]ジオキサボリナン-4-イル)-酢酸 tert-ブチルエステル(式IIの化合物、10 kg、14.82 mol)、即ち、式IIの化合物を、TH(80 L)の中に溶解し、窒素ガスを用いて30分間脱ガスした。水(72 L)中の水酸化ナトリウム(2.84 kg)を上記の溶液に加え、4時間還流させた。この反応混合物を真空下で濃縮して溶媒を除去し、水(150 L)を添加した後、続いてMTBE(50 L)を加えた。層を分離した後、水溶液を真空下に3時間維持し、該溶液を25〜28℃で12時間放置した。形成された沈殿(アトルバスタチンのナトリウム塩)を濾過し、酢酸エチル(70 L)の中に溶解させた。この透明な有機層に、水(40 L)中の酢酸カルシウム(2 kg)の溶液を添加し、40〜45℃で撹拌した。層を分離し、有機層を水(5×100 L)で洗浄した。有機層を蒸発させ、残渣を真空下で乾燥して、非晶質のアトルバスタチンカルシウムを得た。
実施例III
(6-{2-[2-(4-フルオロ-フェニル)-5-イソプロピル-3-フェニル-4-フェニルカルバモイル-ピロリジン-1-イル]-エチル}-2-フェニル-[1,3,2]ジオキサボリナン-4-イル)-酢酸 tert-ブチルエステル(式IIの化合物、500 g、0.7 mol)を、THF(4 L)の中に溶解させ、窒素ガスを用いて30分間脱ガスした。水(3.57 L)中の水酸化ナトリウム(142 g)の溶液を上記の溶液に添加し、2時間還流させた。この反応混合物を真空下で濃縮して溶媒を除去し、水(7.5 L)を添加した後、続いてMTBE(2.5L)を加えた。層を分離した後、水溶液を真空下に1時間維持し、該溶液を12時間室温で放置した。形成された沈殿(アトルバスタチンのナトリウム塩)を濾過し、酢酸エチル(3.5 L)の中に溶解させた。この透明な有機層に、水(2 L)中の酢酸カルシウム(60 g)の溶液を添加し、40〜45℃で撹拌した。層を分離し、有機層を水(5×5L)で洗浄した。有機層を蒸発させ、残渣を真空下で乾燥して、非晶質のアトルバスタチンカルシウムを得た。
