中でも粉末X線回折(XRPD)は、固体の結晶性を測定するための最も感度の良い分析法のうちの1つである。X線が結晶に照射されると、結晶格子面で反射し、互いに干渉しあい、ブラッグ則よって予測される条件を満たす方向の回折線のみ強度が増大し、それ以外は打ち消しあって観測されない。一方、非晶質固体については広範囲の秩序だった回折線は認められない。非晶質固体は、通常、反復する結晶格子の広い範囲の秩序が不存在であるため、ハローパターンと呼ばれるブロードなXRPDパターンを示す。
ここでTG/DTA(示差熱熱重量同時測定)は、熱分析の主要な測定方法のひとつであって、原子・分子の集合体としての物質の重量および熱的性質を測定する方法である。
TG/DTAは医薬活性成分の温度または時間に係る重量および熱量の変化を測定する方法であり、得られたデータを温度または時間に対してプロットすることにより、TG(熱重量)およびDTA(示差熱)曲線が得られる。TG/DTA曲線より、医薬活性成分の分解、脱水、酸化、還元、昇華、蒸発に関する重量および熱量変化の情報を得ることができる。
TG/DTAにおいて、「融点」とは、オンセット温度をいう。
TG/DTAについて、観察される温度、重量変化は、温度変化速度ならびに用いる試料調製技法および特定の装置に依存し得ることが知られている。結晶の同一性の認定においては、全体的なパターンが重要であり、測定条件によって多少変化し得る。

本発明による化合物(I)の製造方法をスキーム1に示した。
本発明によれば、カルバメート誘導体(II)に塩基を添加し、室温~溶媒の沸点以下の温度で1~10時間反応させることにより化合物(I)を得ることができる。塩基としては水酸化リチウム、水酸化ナトリウム、水酸化カリウム、水酸化セシウム等の無機塩基が好ましく、カルバメート誘導体(II)に対して1~10当量のアルカリを水溶液として添加することが好ましい。カルバメート誘導体は親水性溶媒、例えばメタノール、エタノール、2-プロパノール、DMSO等の溶媒に溶解し、上記アルカリ水溶液を添加することで好適に反応させることができる。
カルバメート誘導体(II)の水酸基保護基R1bは特に限定されないが、例えばアセチル基等の塩基で脱保護される保護基を用いると化合物(I)を直接得ることができる。R1bが塩基では脱保護されない保護基の場合、上記の塩基処理の前または処理後に適宜保護基を脱保護すればよい。
カルバメート誘導体(II)は化合物(III)にイソシアネート体(V)を反応させることにより得られる。反応は、化合物(III)の溶液に、化合物(III)に対して0.5~5当量、好ましくは、1.0~1.2当量のイソシアネート体(V)溶液を加え、室温~溶媒の沸点以下の温度で1~10時間反応させる。ここで、例えば、CuCl2のようなルイス酸触媒を0.00005~1当量、好ましくは0.0001~0.1当量、さらに好ましくは0.0001~0.01当量添加することが好ましい。反応溶媒は特に制限はないが酢酸エチル、アセトニトリル、アセトン、トルエン等が使用できる。
ここで用いるイソシアネート体(V)は、下記スキームに従い、
イソシアネート体に代えて、カルバミン酸活性エステル(VI)(式中、R7は置換基を有していてもよいフェニル基)を用いてカルバメート体(II)を調製することもできる。この活性エステルは例えばアミノ体R3-NH2に相当するフェノールのクロロ蟻酸エステルを反応させて得ることができる。
