Abstract
Description
本発明は、サプロプテリンまたはその薬学的に許容される塩、およびそれらの新規合成中間体を調製する新規方法に関する。
サプロプテリン、すなわち式(I)
の化合物を前記式(VI)の化合物に変換するステップを含む方法である。
のジスルホンを得るステップと、次いで塩基と反応させるステップとを含む方法により行うことができる。
のジチオールとの反応を含む方法により調製できる。
(L)−ラムノース1’,3’−プロパンジチオアセタール(XII; n=1)の合成
L−ラムノース一水和物(168.3g、0.92mol)を、強く撹拌しながら37%HCl500ml中の1,3−プロパンジチオール(100g、0.92mol)の混合物に小分けして固体として加える。得られた溶液を、撹拌しながら約20℃で12時間保持する。すでに最初の1時間で、十分な白色沈殿物の形成が観察される。次いで、懸濁液を5〜10℃に冷却し、酸過剰をNaOHおよび氷500mlで中和する。次いで、pH約7の懸濁液を濾過し、固体を水およびイソプロパノール100mlで洗浄する。湿潤固体を真空下で40℃にて16時間乾燥し、収率95%でオフホワイト色の固体として生成物(XII)222gを得る。
1’,3’−プロパンジスルホニル(L)−ラムノースの合成(XIII; n=1)の合成
タングステン酸ナトリウム二水和物(13g、0.04mol)を、(L)−ラムノース1’,3’−プロパンジチオアセタール(XII)(200g、0.79mol)を氷酢酸1.2Lに溶解させることにより得られる溶液に懸濁する。懸濁液を約15℃に冷却し、そこに35%過酸化水素(417mL、4.72mol)を徐々に滴下し、40℃未満の温度を保つ。得られた透明の溶液を約20℃で16時間撹拌する。次いで、H2O2過剰を、チオ硫酸ナトリウム濃縮液を加えることにより失活させる。次いで、溶媒混合物を、約400mLの量まで減圧下で蒸発させる。得られた混合物は、さらなる精製なしに次のステップで直接使用する。
1’,3’−プロパンジスルホニル(L)−ラムノースの合成(XIII;n=1)の合成
(L)−ラムノース−1’,3’−プロパンジチオアセタール(XII)(200g、0.738mol)およびタングステン酸ナトリウム二水和物(12.2g、0.037mol)を氷酢酸(991.6g)に溶解させる。水(48g)を得られた溶液に加え、反応混合物を10〜15℃に冷却する。35%過酸化水素(322.5g、3.32mol)を、20〜30℃の温度を保ちながら少なくとも4時間で加える。次いで、反応混合物を約30〜35℃で加熱し、撹拌しながら約3時間保持する。次いでイソプロパノール(416.7g)を加える。得られた懸濁液を、撹拌しながら30〜35℃で約5時間保持し、次いで少なくとも5時間で20〜25℃に冷却した後、少なくとも3時間で5〜10℃に冷却し、撹拌しながらさらに1時間保持する。懸濁液を冷却し、次いで濾過し、得られた固体をイソプロパノール(314.2g)で洗浄する。
5−デオキシ−L−アラビノース(VI)の合成
例2からのジスルホン(XIII)を含有する懸濁液を、水1Lで希釈し、10〜15℃に冷却し、次いで33%NH3水溶液でpH8〜9にアルカリ化する。濃厚な懸濁液が直ちに形成され、それを出発生成物が完全に消失するまで撹拌しながら約20℃で16時間保持する。次いで、固体を濾過し、水250mlで洗浄する。合わせた水相を酢酸エチルで抽出し、ごく微量のスルホンをも除去する。得られた5−デオキシ−(L)−アラビノース(VI)水溶液はそのまま、L−ビオプテリン、および所望される場合、サプロプテリンを得るためのその後の反応で使用できる。
5−デオキシ−L−アラビノース(VI)の合成
例3からの1’,3’−プロパンジスルホニル(L)−ラムノース(XIII)(209.9g、0.650mol)を水(369.9g)および酢酸エチル(568g)中に分散させる。次いで28%アンモニア(13.8g)をpH8以上になるまで加える。
