(2R)-2-フェニルカルボニルオキシプロピル(2S)-2-アミノ-3-(3,4-ジヒドロキシフェニル)プロパノエートメタンスルホネート(1)の合成
ステップ1:Boc-L-ドーパテトラブチルアンモニウム塩(3)
(2R)-2-フェニルカルボニルオキシプロピル(2S)-2-アミノ-3-(3,4-ジヒドロキシフェニル)プロパノエートメタンスルホネート(1)の再結晶
(2R)-2-フェニルカルボニルオキシプロピル(2S)-2-アミノ-3-(3,4-ジヒドロキシフェニル)プロパノエートメタンスルホネート(1)(19.3g, 42mmol)をアセトニトリル(CH3CN)(400mL)中に懸濁し、水浴中、80℃で加熱した。その後、脱イオン水(4mL)を加えると、大部分が溶解した。溶液を、焼結ガラス漏斗を通して濾過し、未溶解の固体を除去した。溶液を攪拌し、15℃/時の速度で徐々に冷却した。約60℃で、溶液は結晶化し始めた。温度が21℃に達した際、固体を濾過により回収し、アセトニトリル(CH3CN)(100mL)とtert-ブチルメチルエーテル(MTBE)(100mL)で洗浄した。その後、固体を真空下で24時間乾燥すると、結晶の(2R)-2-フェニルカルボニルオキシプロピル(2S)-2-アミノ-3-(3,4-ジヒドロキシフェニル)プロパノエートメタンスルホネート(1) 14.7g(32.3mmol)がオフホワイトの固体として得られた。
(2R)-2-フェニルカルボニルオキシプロピル(2S)-2-アミノ-3-(3,4-ジヒドロキシフェニル)プロパノエートメタンスルホネート(1)の合成
ステップ1:Boc-L-ドーパテトラブチルアンモニウム塩(3)
下側の水層を200Lポリエチレンドラム缶に30Lの分液漏斗を使用して移し、上側の有機層を380Lの反応器に移した。水層を1900Lの反応器に戻し、メチルtert-ブチルエーテル(MTBE)(77kg, 2部)を加えた。温度を22℃(19〜25℃)に調節し、混合物を約1時間穏やかに攪拌した。攪拌を止め、層を約60分かけて分離させた。下側の水層を30Lの分液漏斗を使用して排出した。有機生成物を1,900Lの反応器に移し、1,900Lの反応器中のメチルtert-ブチルエーテル(MTBE)有機層と合わせた。380Lの反応器とポンプラインをメチルtert-ブチルエーテル(MTBE)約20kgですすいで1,900Lの反応器へ移した。水(271kg, 7.0部)中の重炭酸ナトリウム(21.3kg, 0.55部)溶液を、反応器の温度を30℃未満に保持しながら有機層に加えた。温度を22℃(19〜25℃)に調節し、約1時間穏やかに攪拌した。
