実施例1
O−(2−トシルオキシエチル)−N−(トリフェニルメチル)−L−チロシンt−ブチルエステルの製造:
L−チロシン t−ブチルエステル*を、室温、DMF(N,N−ジメチルホルムアミド)中、トリエチルアミンの存在下で、等モル量のトリフェニルメチルクロライドと反応させた。DMF相を4倍量の氷と混合することにより、粗生成物が沈殿し、エタノールから再結晶する。
収率:70%Fp.171℃
(*商業的に入手可能である)
等モル量のN−トリフェニルメチル−L−チロシン t−ブチルエステル及び、エチレングリコール ジ−(p−トルエンスルフォネート)を、アセトン中に溶解した。塩基の存在下で、抽出物の混合物を2日間室温で激しく攪拌した。濾過及び粗生成物含有溶液を蒸発させた後、生成物の精製を低沸点の石油エーテル及び酢酸エチルからなる移動触媒を含むシリカゲルを使って実施した。
収率:60%Fp. 54...64℃
18Fを含む水を40μmolのテトラ−n−ブチルアンモニウム炭酸水素塩の存在下で、蒸発乾固した。引き続き0.5mlのアセトニトリル中の25mg(37μmol)N−トリチル−O−(2−トシルオキシエチル)−L−チロシン t−ブチルエステル溶液を添加し、この溶液を5分間沸騰するまで加熱した。減圧下、約20℃の温度で溶媒を蒸発させ、トリフルオロ酢酸/トリエチルシラン/ジクロルメタンの混合物(1/0.4/2)(v/v/v)の1mLを添加し、10分間攪拌した。9mlのジクロルメタンで希釈した後、溶液をシリカゲル、次いで酸化アルミニウムのカートリッジ(各1g)に導いた。カートリッジを、n−ペンタン/ジエチルエーテル(1/1)溶媒混合物10mlで洗浄した。不活性ガス流によって残りの溶媒を蒸発させ、〔18F〕FET−粗生成物を、35mモルのリン酸三ナトリウム塩溶液を使って溶出し、逆相高圧液体クロマトグラフィーで精製した。〔18F〕FET−生成物画分を、陽イオン交換体(LiChrolut SCX、H+形、1g)に導き、その後滅菌した水で洗浄し、18Fで標識されたアミノ酸を、生理的濃度のリン酸ナトリウム緩衝液を使って溶出し、溶出液を無菌濾過した。
