Description
本願は、2011年3月25日に、日本に出願された特願2011−068878号に基づき優先権を主張し、その内容をここに援用する。
本発明は、嵩密度が高く、保存安定性に優れたグルタミン酸ベンジルエステルN−無水カルボン酸を提供することを目的とする。
CuKα線を線源とする粉末X線回折図形で回折角(2θ°)において、6.5°、13.0°、19.5°にピークを有する結晶多形(A晶)を含み、嵩密度が0.47g/cm3以上であるグルタミン酸ベンジルエステルN−無水カルボン酸の結晶に関し、
A晶を含むグルタミン酸ベンジルエステルN−無水カルボン酸の結晶が、CuKα線を線源とする粉末X線回折図形で回折角(2θ°)において、15.0°、17.3°、18.9°、19.9°、21.2°、23.2°、23.9°、25.0°、27.7°にピークを有する優先配向の異なるA晶を含む混合物である、グルタミン酸ベンジルエステルN−無水カルボン酸の結晶が好ましい。
また、他の結晶化方法として、グルタミン酸ベンジルエステルN−無水カルボン酸を溶媒としてクロロホルムを用いて加熱溶解後、冷却することにより結晶化させる方法でも、目的とする嵩密度の高い結晶多形を得ることができる。
用いるクロロホルムの量は特に制限されないが、通常の再結晶が行える範囲であれば、特に制限されず、グルタミン酸ベンジルエステルN−無水カルボン酸1molに対して1.5L〜3.0Lの範囲が好ましく、1.8〜2.2Lの範囲がさらに好ましい。
実施例1
<粉末X線結晶解析の方法>
実施例2
実施例3
得られた結晶について、実施例1と同様の条件下で粉末X線結晶解析を行った結果を図3に示す。また、結晶の嵩密度は、0.50g/cm3であった。
