・(2S)−2−[(4S)−4−(2,2−ジフルオロビニル)−2−オキソピロリジニル]ブタンアミド151mg(0.65mmol)及びMgCl231mg(0.325mmol)をメタノール約3mLに溶かす。溶媒をゆっくりと蒸発させると、(2S)−2−[(4S)−4−(2,2−ジフルオロビニル)−2−オキソピロリジニル]ブタンアミド:MgCl2:H2O(2:1:4)共結晶のプリズム状で無色のタブレットが得られる。共結晶は、DSC及び単結晶X線回折を介して分析することができる。
・熱分析(Q−1000、TA instrument)を行い、(2S)−2−[(4S)−4−(2,2−ジフルオロビニル)−2−オキソピロリジニル]−ブタンアミド:MgCl2:H2O(2:1:4)共結晶の融点/挙動を決定する。融点は、138〜145℃であることが決定される。
・単結晶X線データ(NONIUS CAD−4/MACH3):C20 H36 Cl2 F4 Mg N4 O8、M=631.74、三方晶系P 32 21、a=8.850(2)オングストローム、b=8.850(2)オングストローム、c=34.827(5)オングストローム、α=90゜、β=90゜、γ=120゜、V=2362.3(8)立方オングストローム、T=293(2)K、Z=3、DC=1.332g/cm3、λ=1.54178オングストローム。194個のパラメーターについての最終R指数は、R1{I>2σ(I)}=0.0498及びwR2=0.147であった。
・(2S)−2−[(4S)−4−(2,2−ジフルオロビニル)−2−オキソピロリジニル]ブタンアミド:MgCl2:H2O(2:1:4)共結晶格子は、エチル及びジフルオロビニル鎖で構成される親油性多層からなる。それらの層間の誘引性ファンデルワース力は、分子構築、並びにマグネシウム陽イオンの配位圈のポリマー鎖により形成される極性層における強い水素結合ネットワークを安定化するのに役立つ。
・この構造に伴うシミュレートしたX線粉末パターンは、以下のピーク、すなわち、2θ 7.60、11.54、11.82、12.60、13.84、15.38、17.18、19.16、20.06、20.20、21.28、23.48、23.80、26.52、28.74、30.54、30.66、31.28、35.84、及び40.46゜(Mercury1.4.1でシミュレートしたデータ)を特徴とする。

・DSCサーモグラム(Q−1000、TA instrument)は、約139℃(ピーク、開始は、135℃である)における共結晶の融解に対応する吸熱遷移を示す、(図1を参照)。このことは、(2S)−2−[(4S)−4−(2,2−ジフルオロビニル)−2−オキソ−ピロリジニル]ブタンアミドの知られている結晶性形態と比較して、融点の約62℃の上昇を表している。
