技术领域
背景技术
在1,5-苯二氮化合物中,已知下述通式(A)表示的化合物及其盐具有优异的促胃液素/CCK-B受体拮抗作用和胃酸分泌抑制作用,不仅作为消化性溃疡的预防治疗药,作为消化器官癌、白血病、下垂体肿瘤、肺小细胞癌、甲状腺癌、神经星形细胞瘤、癌性疼痛等的预防治疗药也是很有效的(专利文献1~5)。
(式中,R1表示直链、支链或环状的烷基,R6表示烷基或酰基烷基,Y表示单键或亚烷基)
作为该化合物(A)的制备方法,已知如上述专利文献1所述,从2-硝基苯胺开始,经过8个工序而得到3-氨基-1,5-苯二氮-2-酮骨架,将其作为中间体,使苯二氮骨架上的1位和5位的氮原子以及3位的氨基形成目标取代基的方法。但是,在该方法中,到3-氨基-1,5-苯二氮-2-酮骨架为止的工序数较多,不适合作为工业上的制法。
另外,上述专利文献2记载了如下方法,即,通过将天冬氨酸作为起始原料,经2-氨基-3-苄氧羰基氨基丙酸而得到3-氨基-2-叔丁氧羰基氨基丙酸,使其与2-氟硝基苯进行反应,进一步进行还原、环合反应,从而形成3-氨基-1,5-苯二氮骨架,在其中依次引入环己烷骨架、频哪酸等。但是,该方法存在不仅工序数多,而且有产生有害物质氟化氢的危险,所以不适于大量合成这样的问题。

具体实施方式
若以反应式表示本发明方法,则如下所示。
(式中,Z表示卤原子,Ar表示芳基,R1、R2、R3、R4、R5、R6、R7、A和Y与上述定义相同。)
对上述反应式中的各取代基进行说明。R1表示直链、支链或环状的烷基,优选碳原子数1~10的烷基,进一步优选碳原子数1~10的直链状或支链的烷基、或者碳原子数3~10的单环或二环的环烷基,特别优选环己基。
R2表示通过还原反应或水解反应生成氨基、烷基氨基或酰基烷基氨基的基团。其中,作为通过还原反应生成上述氨基或取代氨基的基团,可举出硝基、亚硝基、叠氮基、羟基氨基、苄氧羰基氨基、N-苄氧羰基-烷基氨基、N-苄氧羰基-酰基烷基氨基等。另外,作为通过水解反应而生成上述氨基或取代氨基的基团,可举出丁氧羰基氨基、N-丁氧羰基-烷基氨基、N-丁氧羰基-酰基烷基氨基等。其中,特别优选苄氧羰基氨基、N-苄氧羰基-烷基氨基、N-苄氧羰基-酰基烷基氨基。此处,作为烷基氨基,可举出碳原子数1~6的烷基氨基,可以举出甲氨基、乙氨基、丙氨基等。作为酰基烷基氨基,可举出C2-C6链烷酰基-C1-C6烷基氨基,可举出乙酰甲基、丙酰甲基、频哪基等,其中,特别优选频哪基。
作为R3表示的酯残基,可举出烷基、苄基、取代苄基、三烷基甲硅烷基等,更具体而言,可举出C1-C8烷基、苄基、卤代苄基、硝基苄基、三C1-C6烷基甲硅烷基等。
A表示含有磺酰基或羰基的保护基,通常可举出作为氨基的保护基所使用的氨基甲酸酯系保护基、酰胺系保护基或磺酰胺系保护基。更具体而言,可举出对甲苯磺酰基、甲磺酰基等取代磺酰基,苄氧羰基等芳烷氧羰基、丁氧羰基等烷氧羰基,乙酰基等链烷酰基,三氟乙酰基、三氯乙酰基等三卤代乙酰基等。其中,因为-COCX3(X表示卤原子)表示的三卤代乙酰基可选择性地得到化合物(3)并且其脱离反应的收率高,所以特别优选。
在此,X表示卤原子,优选为氟原子或氯原子,特别优选为氟原子。Z表示卤原子,优选为氯原子或溴原子。
作为R4表示的氨基、烷基氨基、酰基烷基氨基,可举出与上述R2相同的基团。另外,R5和R6所表示的烷基、酰基烷基也同样,例如可举出碳原子数1~6的烷基、C2-C6链烷酰基-C1-C6烷基。
作为R7表示的可以具有取代基的芳基以及Ar表示的芳基,可举出苯基、卤代苯基、烷基苯基、硝基苯基等。Y表示单键或亚烷基,可举出单键、二甲基亚甲基、二乙基亚甲基等,特别优选为单键。
在作为起始原料的式(1)的化合物中,R1为环己基、R2为苄氧羰基氨基的化合物是新化合物,例如,可以通过在碱的存在下使2-环己基氨基苯胺与苄氧羰基卤进行反应来制备。另一方面,在式(2)的氮丙啶化合物中,N-三氟乙酰基氮丙啶-2-甲酸苄酯是新化合物,例如可以以Bull.Chem.Soc.Jpn.1978,51,1577中记载的内容为基准,通过在碱的存在下使氮丙啶酯与三卤代乙酸酐进行反应的方法来制备。
化合物(1)与化合物(2)的反应只要在适当的溶剂中、在室温~200℃下进行反应即可,更优选在80℃~110℃下进行反应。作为溶剂,优选为非极性的烃溶剂,更优选为甲苯、二甲苯等芳香族烃系溶剂。
在该化合物(1)与化合物(2)的反应中,为了选择性地发生氮丙啶β位开环反应,优选R1为烷基,特别优选为直链烷基、支链烷基或环烷基,进一步优选在与氮原子键合的碳原子上具有1个氢原子的烷基。因而,R1优选为C1-C8的直链烷基、C3-C8的支链烷基、C3-C6的环烷基,进一步优选为C3-C6的环烷基,特别优选为环己基。另外,为了高效地发生氮丙啶β位开环反应,氮丙啶环的氮原子上的取代基特别优选为三卤代乙酰基。另外,从后述的环合反应的选择性这点出发,该氮丙啶环的氮原子上的取代基A特别优选为三氟乙酰基。
一直以来,已知的是氮丙啶的开环反应(WO97/05129、日本特开平10-203987号公报、J.Chem.Soc.Perkin Trans.1,1997,3219),但是完全不知道如本发明的反应那样,利用苯胺衍生物与N-酰基氮丙啶化合物、特别是与N-三卤代乙酰氮丙啶化合物的氮丙啶开环反应选择性地发生β位开环。
另外,从选择性地得到立体异构体这点出发,优选化合物(1)与化合物(2)的反应。即,若如下述反应式所示,采用化合物(2)的立体异构体,则可选择性地得到化合物(3)的立体异构体。
(式中,R1、R2、R3和A与上述定义相同)。
因此,如果采用化合物(3)的立体异构体,则可选择性地得到化合物(A)的下述立体异构体。
(式中,R1、R6和Y与上述定义相同)
通过使化合物(3)进行还原反应或水解反应,将化合物(3)中的R3转化为R4。该反应中,还原反应例如可以使用在催化剂存在下使氢发生反应的方法(催化还原)和使用还原剂的方法中的任一种,但是优选催化还原。作为催化剂,可举出钯系催化剂或铂系催化剂,例如钯碳、钯、氧化铂、铂碳等。作为反应溶剂,优选为非极性的烃系溶剂,特别优选为甲苯、己烷等芳香族烃系溶剂。
通过使得到的化合物进行环合反应,得到化合物(5)。只要该反应在与上述相同的烃系溶剂中且室温~80℃下进行反应即可。
从化合物(1)与(2)开始到化合物(5)为止的反应可以使用烃系溶剂作为反应溶剂,可以不分离反应中途的产物而连续地进行,因此是非常有利的工业制备方法。
化合物(5)中的R5为氢原子时,通过使化合物(5)与烷基卤或酰基烷基卤进行反应,可以将R5转化为R6。该N-烷基化反应可在碳酸钾、碳酸钠、氢氧化钠等碱的存在下,并且根据需要在四丁基溴化铵等相转移催化剂的存在下进行。作为反应溶剂,可使用四氢呋喃、二烷等醚系溶剂,甲苯、乙酸乙酯、N,N-二甲基甲酰胺、二甲基亚砜等。另外,也可以在使用四丁基溴化铵等相转移催化剂的水-甲苯系等二相体系中进行。反应通常可以在-78~150℃的范围内进行。
可以使化合物(5)的保护基A脱离而得到化合物(6)。保护基A的脱离反应优选通过水解而进行脱离。该反应只要按照一般的水解反应,例如加入盐酸等酸,并且在0~100℃下进行即可。作为溶剂,使用乙醇等醇类,氯仿等卤代烃,二烷、二乙基醚等醚类,甲苯、二甲苯等芳香族烃。
从化合物(6)开始到化合物(A)为止的反应利用(a)使化合物(6)与化合物(7)进行反应的方法;(b)使化合物(6)与卤代甲酸芳酯(9)进行反应而得到化合物(10),然后再使其与化合物(8)进行反应的方法中的任一种方法来进行(参照WO2001/040197)。
化合物(6)与化合物(7)的反应,例如优选在三乙胺、碳酸钾等碱的存在下进行。反应在0℃~回流温度的范围内进行,作为反应溶剂,使用二甲基甲酰胺、二甲基亚砜等。
化合物(6)与化合物(9)的反应优选在碳酸钾、三乙胺等碱的存在下,在四氢呋喃、二甲基甲酰胺等溶剂中进行。反应温度优选为0℃~回流温度。
化合物(10)与化合物(8)的反应优选在碳酸钾、三乙胺等碱的存在下,在四氢呋喃、二甲基甲酰胺等溶剂中进行。反应溶剂为0℃~室温即可。
可以利用常规方法将得到的化合物(A)转化为碱金属盐、碱土金属盐等,优选转化为钙盐,特别优选依次加入氨水和氯化钙溶液而形成钙盐。
在上述反应式中,下述化合物(1a)、(2a)、(3a)和(5a)或其盐是新化合物,可用作化合物(A)的制备中间体。
(式(1a)、(2a)中,Cbz表示苄氧羰基,Bn表示苄基)
(式(3a)中,Ra表示氢原子或苄氧羰基,R3a表示氢原子或苄基,X表示卤原子)
