Abstract
Description
図2は、N−(トランス−4−イソプロピル−シクロヘキシルカルボニル)−D−フェニルアラニンのB−型結晶の赤外吸収スペクトルを示す。
B−型のナテグリニド結晶形の融点(mp)は、128〜131℃の範囲にあることがDSC法により測定された。
R’−型のナテグリニド結晶は、以下のように製造され得る:
H−型のナテグリニド結晶を、エタノールおよびトルエン(50%(容積)のエタノールおよび50%(容積)のトルエン;160mg/mLのナテグリニド)の混合物中で室温にて撹拌しながら溶かす。すべての固体が溶けた後に、1%ヒドロキシプロピルメチルセルロースを含有する水を添加して、沈澱を生じさせる(使用されたエタノール−トルエンの容積の約7倍)。さらに2時間撹拌した後、沈澱した固体を真空濾過により集め、洗浄し、そして減圧下で50℃にて一夜乾燥するとR’−型の結晶を得る:融点108℃。
