N2−N,N−ジメチルアミノメチレン−L−ネオプテリン(R1がジメチルアミノメチレン−イミン基である、式6の化合物)の調製を、11.68gのL−ネオプテリン及び850mlの乾燥N,N−ジメチルホルムアミドを含むフラスコに、15.8mlのN,N−ジメチルホルムアミドジエチルアセタールを加えることによって調製した。全ての出発物質が溶解するまで、混合物を室温で撹拌した。室温で6時間撹拌した後、280mlの乾燥メタノールを加え、反応混合物及び混合物を、更に12時間撹拌した。全ての溶媒を蒸発させた後、反応混合物からの残渣を、500mlのジクロロメタンに懸濁し、次いで、懸濁した物質を集め、150mlのジクロロメタンで洗浄し、生じた生成物を40℃で減圧乾燥し、11.23gのN2−N,N−ジメチルアミノメチレン−L−ネオプテリンを得た。
第一級ヒドロキシル基の選択的保護を、実施例1で調製した、2−アミノ保護L−ネオプテリンを用いて行った。最初に、10gのN2−N,N−ジメチルアミノメチレン−L−ネオプテリンを、250mlの乾燥N,N−ジメチルホルムアミドに懸濁し、次いで、4.9gのイミダゾール及び10gのt−ブチルジフェニルクロロシランを反応混合物に加えることにより、N2−N,N−ジメチルアミノメチレン−3’O(t−ブチル−ジフェニルシリル)−L−ネオプテリンを調製した。反応混合物を室温で2時間撹拌した後、0.5gのイミダゾール及び1gのt−ブチルジフェニルクロロシランを加えた。反応混合物を室温で更に14時間撹拌した後、反応混合物を蒸発して乾燥し、残渣を、9:1〜6:4のジクロロメタン/メタノールの勾配を用いたシリカゲルによるフラッシュクロマトグラフィーにより精製した。生成物画分をプールして濃縮した。残渣を100mlのイソプロパノールい懸濁し、生成物を集め、イソプロパノールで洗浄し、40℃で減圧乾燥し、9.3gのN2−N,N−ジメチルアミノメチレン−3’(t−ブチル−ジフェニルシリル)−L−ネオプテリンを得た。
また、第一級ヒドロキシル基の選択的保護を、実施例1で調製した、2−アミノ保護L−ネオプテリンを用いて行い、選択的保護の後、2−アミノ基の脱保護を、同じフラスコ中で行い、3’O−(t−ブチル−ジフェニルシリル)−L−ネオプテリンを得た。
反応混合物を室温で14時間撹拌した後、反応混合物を濃縮して乾燥し、粗精製のN2−N,N−ジメチルアミノメチレン−3’(t−ブチル−ジフェニルシリル)−L−ネオプテリンを、160mlのエタノールに溶解した。エタノールに溶解することにより、15gの塩化亜鉛を反応フラスコに加え、混合物を80℃で3時間加熱した。3時間のコースの間、固体は混合物から単離された。次いで、懸濁液を58℃に冷却し、固体を集め、100mlのエタノールで洗浄し、40℃で減圧乾燥し、5gの3’(t−ブチル−ジフェニルシリル)−L−ネオプテリンを得た。3’(t−ブチル−ジフェニルシリル)−L−ネオプテリンの他の5gの画分は、室温で24時間残した後、ろ過から得られた。
50mlのアセトン−ジメチルアセタール中の10gの3’(t−ブチル−ジフェニルシリル)−L−ネオプテリン(実施例3に従って調製)を含む反応フラスコに、3.8gのパラ−トルエンスルホン酸を加えることにより、第二級ヒドロキシル基の保護を行い、1’2’−イソプロピリデン−3’O−(t−ブチル−ジフェニルシリル)−L−ネオプテリンを調製した。反応混合物を、室温で14時間撹拌した。生じた固体を集め、30mlのアセトン−ジメチルアセタールで洗浄し、35℃で減圧乾燥し、6.5gの1’2’−イソプロピリデン−3’(t−ブチル−ジフェニルシリル)−L−ネオプテリンを得た。
L−ネオプテリンの第一級ヒドロキシルのチオエーテルへの変換を行い、6−((1R,2R)−1,2−ジヒドロキシ−3−フェニルチオプロピル)−2−〔(メチルエチル)アミノ〕−3−ヒドロプテリジン−4−オン(図4において“15”と表示された化合物)を調製した。50グラムの6−((2S,1R)−1,2,3−トリヒドロキシプロピル)−2−〔(1Z)−1−アザ−2−(ジメチルアミノ)ビニル〕−3−ヒドロキシプテリジン−4−オン(DMA−ネオプテリン、図2において“6”と表示された化合物)を含むフラスコに、400mlのジメチルアミノアセテートをフラスコに加えた。この撹拌混合物に、1モル当量のジフェニルジスルフィド及びトリブチルホスフィンをフラスコに加えた。室温で、DMA−ネオプテリンがジメチルアミノアセテートに低い溶解性を示すことがわかった(約3.5mg/ml)。ジメチルアミノアセテート中で、チオエーテル生成物がそれ以上に溶解できると信じられている。反応混合物を、室温で4時間撹拌した。9グラムのチオエーテル生成物が単離された。
実施例5で調製されたチオエーテル生成物を、下記手段に従ってラネーニッケルで還元した。チオエーテル(9グラム、22ミリモル)をフラスコに加え、フラスコを360mlのエタノールで満たした。エタノール中のチオエーテルの撹拌混合物に、エタノール中の90グラムのラネーニッケルを加え、反応混合物を、圧力5バールの水素の雰囲気下に置いた。反応混合物を17時間撹拌した。
