Description
DOTAの合成
100mlの水及び100gのサイクレン塩酸塩をフラスコに投入する。反応物を0〜10℃に冷却し、溶液のpHを水酸化ナトリウムで10〜10.5に調整する。pHを水酸化ナトリウム溶液で10〜10.5に保ちながら、クロロ酢酸を反応物に加える。徐々に反応物の温度を70〜75℃に上げ、反応完了まで維持する。反応物を冷却し、反応物のpHを濃塩酸で0.75未満に調整し、分離した固体のDOTA塩酸塩をろ取する。固体を水から再結晶化させ、硫酸塩灰分の含有が0.10%未満であることを確認する。次いで、固体を800mlの水に溶解し、Amberlyst A26 OH樹脂で溶液のpHを2.5〜3.0程度に調整して、塩酸塩を含まないキレート剤を得る。次いで、生成物をろ過し、得られたろ液を200〜300mlの水に蒸留し、アセトンを加えて固体を沈殿させる。固体をろ取・乾燥することで、硫酸塩灰分が0.1%未満であり、ナトリウム及び塩化物の含有量が200ppm未満である、望ましい純度の表題の生成物が得られる。
BOPTAの合成
100mlの水及び50gのN−[2−[(2−アミノエチル)アミノ]エチル]−O−(フェニルメチル)セリンをフラスコに投入する。反応物を0〜10℃に冷却し、溶液のpHを水酸化ナトリウム溶液で10.5〜11.5に調整する。pHを水酸化ナトリウム溶液で10.5〜11.5に保ちながら、クロロ酢酸を反応物に加える。徐々に反応物の温度を70〜75℃まで上げ、反応完了まで維持する。反応物を冷却し、反応物のpHを濃塩酸で0.75未満に調整し、アセトンを投入する。分離した固体のBOPTA塩酸塩をろ過する。固体を水から再結晶化させ、硫酸塩灰分の含有が0.10%未満であることを確認する。次いで、前記固体を800mlの水に溶解し、Amberlyst A26 OH樹脂で前記溶液のpHを2.0程度に調整する。次いで、生成物をろ過し、ろ液を200〜300mlの水に蒸留し、アセトンを加えて固体を沈殿させる。以上のように得られる固体をろ取・乾燥することで、硫酸塩灰分が0.1%未満である、望ましい純度の生成物が得られる。
