Description
式(3):
参考例で得られた油状形態の化合物(1)17.82gをトルエン20.80gに溶解し、攪拌しながらヘキサン30.50gを23℃で滴下した。−5℃まで冷却後、後述の実施例2で取得した種晶(0.02g)を添加したところ、(3S,4S)−4−[(1R)−1−(p−クロロフェニルチオカルボニル)エチル]−3−[(1R)−1−トリメチルシリロキシエチル]−1−ピバロイルオキシメチルオキシカルボニルメチル−2−アゼチジノン(1)が結晶として析出した。析出した結晶を濾取し、少量のヘキサンで洗浄した後真空乾燥を18時間行うと、白色の結晶形態の化合物(1)が13.7g得られた。得られた結晶は、偏光顕微鏡による観察で偏光性のある針状の結晶であった。融点:64℃。また、得られた結晶のNMRは以下の通りであった。
1H−NMR(CDCl3)δ:0.14(9H, s)、1.17(9H, s)、1.27〜1.30(6H, m)、3.05〜3.16(2H, m)、3.85(1H, d, J=18.3Hz)、4.10(1H, dd, J=2.7, 5.4Hz)、4.14〜4.20(1H, m)、4.32(1H, d, J=18.3Hz)、5.75(2H, s)、7.30(2H, d, J=8.3Hz)、7.38(2H, d, J=8.3Hz)。

測定条件:使用X線 Cu・Kα線、X線強度 40kV、100mA、角度域 2θ=3〜80°、走査速度 2°/分、サンプリング間隔 0.02秒、ダイバージェンススリット 1.0°、レシーピングスリット 0.6°、スキャッタスリット 1.0°
結果を表1に示す。
参考例と同様な方法で得られた(3S,4S)−4−[(1R)−1−(p−クロロフェニルチオカルボニル)エチル]−3−[(1R)−1−トリメチルシリロキシエチル]−1−ピバロイルオキシメチルオキシカルボニルメチル−2−アゼチジノン(1)を含有するトルエン溶液11.0gを減圧濃縮し、−20℃で終夜冷却したところ、白黄色の塊状物1.2gが得られた。この塊状物を潰しながら、少量のヘキサンで洗浄した後真空乾燥行うと、白色の固体が得られ、偏光顕微鏡で観察したところ偏光性のある針状の結晶が認められた。
参考例で得られた油状形態の(3S,4S)−4−[(1R)−1−(p−クロロフェニルチオカルボニル)エチル]−3−[(1R)−1−トリメチルシリロキシエチル]−1−ピバロイルオキシメチルオキシカルボニルメチル−2−アゼチジノン(1)に実施例2で取得した種晶を極微量添加し、室温下(25℃)で放置した。2時間後、白色の塊状物が得られた。得られた塊状物を潰しながら少量のヘキサンで洗浄した後真空乾燥を行うと白色の固体が得られ、偏光顕微鏡による観察したところ偏光性のある針状の結晶が認められた。
実施例1で得た結晶形態の化合物(1)約40〜50mgをガラス瓶に秤量した後、窒素ガス雰囲気下50℃にて21日間放置した。得られた結晶は、外観の色、形状とも変化はなかった。また、初日の結晶形態の化合物(1)の残存率を100%として得られた結晶の残存率を高速液体クロマトグラフィー(HPLC)にて測定した。ここでいう残存率はHPLCの面積百分率を基準にしており、初日の化合物(1)の面積百分率に対する値である。
