本発明の式(3)で表わされる光学活性スルホンアミド誘導体の製造に適用可能な溶剤としては、ジクロロメタン又はトルエンが好ましく、さらにジクロロメタンとトルエンの混合溶剤が好ましい。溶剤の使用量としては、反応に具する式(1)で表わされるアセトフェノン誘導体に対して、20〜100重量倍量使用するとよい。
本発明の製造後の後処理としては、公知の方法であれば特に制限されないが、例えば、飽和塩化アンモニウム水溶液を加えて反応を停止、塩化メチレンで抽出、得られた有機相を飽和食塩水で洗浄、硫酸ナトリウム上で乾燥、濃縮した後、テトラヒドロフラン中、テトラ−n−ブチルアンモニウム処理、次いで溶媒留去後、シリカゲルカラムクロマトグラフィーにて精製することにより、目的物の式(3)で表わされる光学活性スルホンアミド誘導体を得るとよい。
