(3'位の保護- 3'-O-(tert-ブチルブトキシカルボニル)ゲムシタビンの製造)
塩酸ゲムシタビン(50グラム)のDM水(200mL)とジオキサン(800ml)との撹拌混合液に、K2CO3(115.3グラム、0.835mol)、続いてBoc無水物(58.3グラム、0.267mol)を25〜30℃で添加し、得られた混合液を同温度で48時間撹拌した。反応終了後、DM水(600ml)を添加し、反応混合液をEtOAc(750ml)で抽出した。有機層を分離し、Na2SO4で乾燥させ、減圧下で濃縮乾固した。残渣を25〜30℃に冷却し、アセトン(150ml)で処理し、減圧下で蒸留した。さらに得られた残渣をアセトンとヘプタンとの混合液、続いてDCMからスラリー化し、表題化合物を得た(51.5グラム;85%)。
HPLCによる純度:93%。
(3'位の保護- 4-N-3'-O-ビス(tert-ブチルブトキシカルボニル)ゲムシタビンの製造)
3'-O-(tert-ブチルブトキシカルボニル)ゲムシタビン(25グラム)のジオキサン(375mL)撹拌溶液に、Boc無水物(75グラム、0.344mol)を25〜30℃で添加した。反応混合液を40〜45℃で90時間維持した。反応終了後、DM水(300mL)を添加し;混合液をEtOAc(375 ml)で抽出した。有機層を分離し、Na2SO4で乾燥させ、減圧下で濃縮乾固した。得られた残渣を25〜30℃に冷却し、EtOAc:ヘプタン混合液中でスラリー化し、表題化合物を得た(21.7グラム、68%)。
HPLCによる純度:97.09%。
(4-N-3'-O-ビス(tert-ブトキシカルボニル)ゲムシタビンを経てのゲムシタビン-[フェニル(ベンゾキシ-L-アラニニル)] ホスフェートの製造):
L-アラニンベンジルエステル塩酸塩(19.7グラム、0.0914mol)のDCM(200ml)懸濁液に、ジクロロフェニルホスフェート(19.6グラム、0.0928mol)を25〜30℃で充填し、-70℃〜約-75℃に冷却した。TEA(18.5グラム、0.1825mol)を、反応混合液に約-75℃〜-70℃で添加し、同温度で1時間、および25〜30℃で2時間撹拌し、反応塊を減圧下で濃縮した。得られた残渣をDIPE(200ml)で処理し、減圧下で濾過および濃縮し、窒素下で0〜7℃で保存した。
HPLCによる純度:99.68%(両ジアステレオマーの約1:1の比率の混合物)。
(3'-モノ保護ゲムシタビンを経てのゲムシタビン-[フェニル(ベンゾキシ-L-アラニニル)]ホスフェートの製造):
L-アラニンベンジルエステル塩酸塩(12.54グラム、0.0583mol)のDCM(125 ml)懸濁液に、ジクロロフェニルホスフェート(13.47グラム、0.0638mol)を25〜35℃で充填し、-70℃〜約-78℃に冷却した。TEA(11.76グラム、0.1164mol)を、反応混合液に-70℃〜約-75℃で添加し、同温度で1時間、および25〜35℃で2時間撹拌し、反応塊を濃縮した。得られた残渣をMTBE(200ml)で処理し、減圧下で濾過および濃縮し、窒素下で2〜8℃で保存した。
HPLCによる純度:98.24%(両ジアステレオマーの約2:1の比率の混合物)。
