Description
発明の概要
本発明は、4−(3,4−ジクロロフェニル)−2−[2−(4−メチルピペラジン−1−イル)−ベンジリデン]−チオモルホリン−3−オンのクエン酸塩に関する。本発明のクエン酸塩は、無水又は殆ど無水の多形である。
δ 179.3、177.0、171.6、164.0、151.0及び144.1。
(i)適した溶媒中に溶解された4−(3,4−ジクロロフェニル)−2−[2−(4−メチルピペラジン−1−イル)−ベンジリデン]−チオモルホリン−3−オンを、クエン酸と接触させ;そして
(ii)形成した結晶を収集すること;
の工程を含んでなる、4−(3,4−ジクロロフェニル)−2−[2−(4−メチルピペラジン−1−イル)−ベンジリデン]−チオモルホリン−3−オンのクエン酸塩の調製のための方法にも関する。
発明の詳細な説明
化合物、4−(3,4−ジクロロフェニル)−2−[2−(4−メチルピペラジン−1−イル)−ベンジリデン]−チオモルホリン−3−オンは、セロトニン−1D受容体(5−HT1D受容体)のアンタゴニストであり、そして多くのCNS疾病、疾患及び症状の治療に有用である。この化合物の遊離塩基及びその塩酸塩は、1998年4月9日に公開された国際特許出願公開WO98/14433(その全てが参照により本明細書に記載されているものとする)に記載されている方法によって調製することができる。
示差走査熱量分析
本発明のクエン酸塩の固体状態における熱的挙動を、示差走査熱量分析(DSC)によって調査した。本発明の塩の軌跡を図1に示す。DSCの温度記録は、Mettler Toledo DSC 821e(STARe System)で得た。一般的に、1ないし10mgの間の試料を、小さいピンホールを持つ型押ししたアルミニウム皿中で調製した。測定は、毎分5℃の加熱速度で30ないし300℃の範囲で行った。
粉末X線回折パターン
本発明のクエン酸に対する粉末X線回折パターンを、銅放射CuKα、固定スリット(1.0,1.0、0.6mm)、及びKevexソリッドステート検出器を備えた、Bruker D5000回折計(Bruker AXS,Madison,Wisconsin)を使用して収集した。データを、3.0ないし40.0度の2シータ(2θ)で、0.04度の間隔及び1.0秒の段階時間(step time)を使用して収集した。
表II.クエン酸塩の代表的な粉末X線回折強度及びピーク位置
本発明のクエン酸塩の単結晶を得て、そしてX線回折によって分析した。代表的な結晶を調査し、そして1Å毎のデータの組(最大sinΘ/λ=0.5)をSiemens R4RA/v回折計で収集した。原子散乱係数は、International Tables for X−Ray Crystallography,Vol.IV,pp.55,99,149(Birmingham:Kynoch Press,1974)から取った。単結晶について集められたデータから、粉末X線回折パターンを計算して、実際に測定した回折パターンと比較した。
固体NMR
クエン酸塩を、固体NMR法によって分析した。約300mgの試料を、7mmのZrOスピナに緊密に充填した。13C NMRスペクトルを、大口径Bruker Avance DRX 500MHz NMR分光計中に位置したBruker 7mm WB MASプローブで交差分極マジック角度回転(CPMAS)を使用して295Kで測定した。試料を15.0KHzでスピンした。交差分極接触時間は、1ミリ秒に設定した。大部分の試料に対して合計512のスキャンを行い、約30分の取得時間となった。スペクトルを、アダマンタンの外部標準(δ 29.5ppm)を使用して参照し、最も高磁場側のメチルのシグナルを29.5ppmに設定した。
4−(3,4−ジクロロフェニル)−2−[2−(4−メチルピペラジン−1−イル)−ベンジリデン]−チオモルホリン−3−オンのクエン酸塩
頂部に機械式撹拌器を備えた1リットルの丸底フラスコで、4−(3,4−ジクロロフェニル)−2−[2−(4−メチルピペラジン−1−イル)−ベンジリデン]−チオモルホリン−3−オンの遊離塩基(30.14g;0.067mol;国際特許出願公開WO98/14433に記載されている手順によって調製)を、525mlの2−プロパノール中に溶解した。溶液を撹拌し、50℃に加熱した。クエン酸(16.2g;0.084mol)を、得られた透明な溶液に分割して加え、そして反応混合物を冷却させ、そして室温で18時間粒状化した。沈殿した固体の試料をDSCによって試験して、未反応の遊離塩基が存在しているか否かを確認してから、白色の結晶質の固体生成物を収集した。濾過後、固体生成物を2−プロパノール(100ml)で洗浄し、そして45℃で窒素置換した真空下で乾燥した。表題のクエン酸塩を94%収率(40.6g;0.063mol)で得た。
