一般手順1
DMF中フマル酸モノメチル(MMF)(1.0当量)およびHBTU(1.5当量)の混合物(25ml/gのMMF)にHuenigs塩基(2.0当量)を添加した。暗褐色溶液を10分間撹拌して、茶色の懸濁液に変わった後、アルコール(1.0〜1.5当量)を添加した。反応を室温で18時間撹拌した。水を添加して生成物を3回、酢酸エチルに抽出した。合わせた有機層を水で3回洗浄し、硫酸マグネシウムで乾燥させ、ろ過して真空下、45℃で濃縮し、粗生成物を得た。粗生成物を、シリカクロマトグラフィーで精製し、いくつかの場合は、ジエチルエーテルを用いた粉砕によりさらに精製し、所望のきれいなエステル生成物を得た。全てのアルコールは市販品であったかまたは公知の文献の手法に従って作製した。
ジエチルエーテル中のエステル生成物(25ml/g)の混合物にジエチルエーテル中2M HCl(1.5当量)を添加した。混合物を室温で2時間撹拌した。溶媒をデカンテーションして、より多くのジエチルエーテルを添加し、溶媒を再度デカンテーションした。次いで残存混合物を真空中45℃で濃縮し、真空オーブン中55℃で18時間さらに乾燥させ、固形HCl塩を得た。
磁石スターラーおよび窒素導入口/排出口を適合させた100mL、一口丸底フラスコに、新たに調製したモノ-メチル塩化フマリル(4.9g、33mmol)を含む11mLのMTBE溶液および50mLのさらなるMTBEを、20℃で添加した。得られた黄色の溶液を氷水浴で<20℃に冷却した。次いで、アルコール(33mmol、1当量)をシリンジにより約10分かけて滴下した。反応混合物を<20℃で10分間撹拌し、その後冷却槽を除き、反応を20℃に温め、20℃で16時間撹拌した。RTで16時間後、TLCにより反応は完了したように思われた。反応混合物を媒体ガラス溶融漏斗により濾過してオフホワイトの固体を回収した。該固体を真空オーブン中25℃で一晩かけて乾燥させ、HCl塩として最終生成物を得た。全てのアルコールは、市販品であったか、または公知の文献の手順に従って作製した。
フマル酸モノメチル(MMF)(1.3当量)、アルキルメシレート(1当量)および炭酸カリウム(1.5当量)のアセトニトリル中の混合物(50ml/gのMMF)を還流で一晩加熱した。混合物を酢酸エチルと炭酸水素ナトリウム飽和水溶液の間で分離して、有機相を乾燥させた(MgSO4)。減圧下での溶媒の濾過および除去により粗生成物を得て、これをそれぞれの場合にシリカクロマトグラフィーで精製した。
フマル酸モノメチル(MMF)(1.3当量)、アルキル塩化物(1当量)および炭酸カリウム(1.5当量)のアセトニトリルまたはジメチルホルムアミド中の混合物(50ml/gのMMF)を20〜65℃で一晩加熱した。混合物を酢酸エチルと炭酸水素ナトリウム飽和水溶液の間で分離して、有機相を乾燥させた(MgSO4)。減圧下での溶媒の濾過および除去により粗生成物を得て、これをシリカクロマトグラフィーによりさらに精製した。
明細書に記載されるNMRスペクトルは、当該技術分野に公知の標準的な技術を使用して、Varian 400MHz NMR分光器により得た。
