Description
500ml容量の装置の中に22gの1−[(1S)−3−ヒドロキシピロリジン−1−イル]−(2S)−2−メチルアミノ−2−フェニルエタンを予め入れておき、そして150mlのテトラヒドロフランに溶解させる。攪拌しながら150mlのテトラヒドロフランと24.1gのジフェニルアセチルクロリドとよりなる溶液を10−20℃において1時間の間に滴加し、その際最初に沈殿物が形成されるけれどもこれは反応の経過とともに再び溶液になる。反応の終り頃に再び沈殿物が形成される。この混合物を室温において更に12時間にわたり攪拌する。次いでこれを約5℃に冷却し、そしてその沈殿した生成物を吸引濾過分離する。この分離された生成物を約100mlのテトラヒドロフランで洗浄し、そして乾燥させる。このようにして39gの粗生成物が得られる。このものを約250mlのエタノールと1gの活性炭とを用いて再結晶させる。
収量 :33gのN−メチル−N−[(1S)−1−フェニル−2−{(3S)−3−ヒドロキシピロリジン−1−イル}エチル]−2,2−ジフェニルアセトアミドヒドロクロリド (理論値の73.2%)
融点 :196−200℃融解熱:100J/gpKa :7.420℃での水の中の溶解度:1.16g/100ml20℃でのメタノールの中の溶解度:6.31g/100ml

9gの1−[(1S)−3−ヒドロキシピロリジン−1−イル]−(2S)−2−メチルアミノ−2−フェニルエタンと40mlのテトラヒドロフランとよりなる、0℃ないし8℃に冷却された反応溶液に、10.5gのジフェニルアセチルクロリドと17mlのテトラヒドロフランとよりなる溶液を攪拌しながら75分間の間に反応溶液へゆっくりと滴加する。次いでこの混合物をその同じ温度において更に120℃後攪拌する。この間に沈殿物として析出した反応生成物は吸引濾過分離して乾燥する。このようにして17gの粗生成物がえられるが、これを180mlのエタノールから再結晶させる。この再結晶の間にその調製された生成物は安定な第4型結晶として50℃において析出する。
収量 :13gのN−メチル−N−[(1S)−1−フェニル−2−{(3S)−3−ヒドロキシピロリジン−1−イル}エチル]−2,2−ジフェニルアセトアミドヒドロクロリド (理論値の70.6%)
