Abstract
Description
−式(I)の化合物を、(7−メトキシ−1−ナフチル)アセトニトリルから出発するただ一つの工程で、85%を上回る優れた収量で、工業的規模で得るのを可能にする。したがって、この新規な方法は、式(I)の化合物を、7−メトキシ−テトラロンから出発する3工程のみで製造するのを可能にする。
−得られた式(I)の化合物は、欧州特許出願公開第1 564 202号公報に記載された結晶形態の特性を、再現性良く有する。
−開発された操作条件により、反応の主要な副次的生成物、すなわち二つの中間体どうしの二量体化から生じるN,N−ビス[2−(7−メトキシ−1−ナフチル)エチル]アセトアミドの形成を最小化するのが可能になる。先験的には、(7−メトキシ−1−ナフチル)アセトニトリルから出発して式(I)の化合物を、その後の薬学的な用途に適合する純度条件で直接得ようと考えることは、反応をワンポット反応として実施するときに規模が劇的に増大するこの副次的反応がまさに存在することを考慮すると、実際には非常に困難であって、式(I)の化合物の医薬としてのその後の用途に許容され得る、二量体化された化合物のための不純物レベルに到達するには、操作条件に関する長期間の非常に詳細な研究が必要であったのである。
工程A:(7−メトキシ−3,4−ジヒドロ−1−ナフチル)アセトニトリル
670リットル入り反応器に、トルエン中の7−メトキシ−1−テトラロン85.0kg、シアノ酢酸60.3kg、およびヘプタン酸15.6kgを、ベンジルアミン12.7kg(またはアニリン11.0kg)の存在下で導入した。混合物を還流にて加熱した。出発物質がすべて消失したとき、溶液を冷却し、ろ過した。得られた沈殿を、トルエンで洗浄し、次いで、得られたろ液を2N水酸化ナトリウム溶液、次いで水で、中性になるまで洗浄した。溶媒を蒸発し去った後、得られた固体を、エタノール/水(80/20)混合物から再結晶させて、標記生成物を、90%の収量、および99%を越える化学的純度で得た。
融点:48〜50℃
670リットル入り反応器に、トルエン中の5%炭素担持パラジウム12.6kgを導入し、これを、還流にて加熱し、次いで、トルエンに溶解した(7−メトキシ−3,4−ジヒドロ−1−ナフチル)アセトニトリル96.1kgを加え、またメタクリル酸アリル63.7kgも加えた。反応を、還流にて継続し、蒸気相クロマトグラフィーによって追跡した。出発物質がすべて消失したとき、反応混合物を、周囲温度まで冷却し、次いでろ過した。トルエンを蒸発し去った後、得られた固体残渣を、エタノール/水(80/20)混合物から再結晶させて、標記生成物を、91%の収量、および99%を越える化学的純度で得た。
融点:83℃
8リットル入り反応器に、ラネーニッケル136g、エタノール2.06L、および水0.23Lを導入した。70℃、かつ30バールの水素下で撹拌しつつ、工程Bで得られ、無水酢酸(2.4L)に溶解した化合物(0.8kg)を徐々に加えた。添加の終点で、反応混合物を、30バールの水素下で1時間撹拌した。次いで、反応器を減圧に付し、液体をろ過した。混合物を濃縮した後、残渣を、エタノール/水の35/65混合物から晶出させて、標記生成物を、89%の収量、および99%を越える化学的純度で得た。
融点:108℃
Bruker AXS社のD8なる高分解能回折計を用い、以下のパラメーター:2θに関して3〜90°の角度範囲、0.01°のステップ、および1ステップあたり30秒でデータ記録を実施した。実施例1で得たN−[2−(7−メトキシ−1−ナフチル)エチル]アセトアミドの粉末を、透過搭載支持具上に沈着させた。X線源は、銅管であった(λCuKα1=1.54056Å)。搭載は、前方モノクロメーター(Ge(111)結晶)、およびエネルギー分解型固体式検出器(MXP−D1、Moxtec−SEPH)を含む。化合物は、充分に結晶化されていて、半幅値は、2θに関して0.07°のオーダーであった。
−単位胞の結晶構造:単斜晶系
−単位胞のパラメーター:a=20.0903Å、b=9.3194Å、c=15.4796Å、β=108.667°
−空間群:P21/n
−単位胞内の分子数:8
−単位胞の体積:Vunit cell=2746.742Å3
−密度:d=1.13g/cm3
実施例1で得た化合物の結晶形態を、Siemens D5005なる回折計(銅の対陰極)を用いて測定され、面間隔d、ブラッグ角2θ、および相対強度(最も強い線に対する百分率として表される)の単位で表される、下記の粉末X線回折図表によって特徴付けた:
