[0118] 将溶于甲醇的苯并茚腈溶液(12L)和Κ0Η溶液(844g Κ0Η溶于4.25L水)装入配有加 热/冷却系统、机械搅拌器、冷凝器和热电偶的50-L圆柱形反应器。搅拌反应混合物并加热 至回流(温度72.2°C)。反应的进行通过TLC来监测(为了观测TLC,用3M HC1酸化lmL至2mL反 应混合物至pH为1至2并且用乙酸乙酯萃取。乙酸乙酯萃取物被用于TLC;洗脱剂:甲醇/ CH2C12; 1:9并由PMA的10%乙醇溶液显色)。反应完全(约5小时)之后,将反应混合物冷却至-5 °〇至1〇1并在搅拌时用盐酸溶液(3M,3.1L)淬灭反应混合物。在50°C至55°C条件下,真空浓 缩所述反应混合物以获得大约12L至14L浓缩物。将所述浓缩物丢弃。
[0119]用水(7L至8L)稀释水层并用乙酸乙酯(2X6L)萃取水层以除去溶于乙酸乙酯的杂 质。向水层加入乙酸乙酯(22L)并通过在搅拌时加入3M HC1 (1.7L)将反应混合物的pH调节 为1至2。分离有机层并用乙酸乙酯(2X11L)萃取水层。用水(3X10L)洗涤合并的有机层并 随后用NaHC0 3溶液(30gNaHC03溶于12L水中)洗涤合并的有机层。再用饱和NaCl溶液(3372g NaCl溶于水(12L)中)进一步洗涤所述有机层并通过无水Na2S〇4(950g至1000g)干燥所述有 机层,过滤一次。
[0120] 将滤液转移至配有机械搅拌器、冷凝器和热电偶的72-L反应器中。将活性碳(110g 至113g)加至反应器中的曲前列素溶液中。将悬浮液加热至回流(温度为68°C至70°C)至少 一小时。使用乙酸乙酯在烧结玻璃漏斗中制备用于过滤的Ce]ite;R'545(3〇〇g至6〇〇g)。通过 01他气545垫过滤热悬浮液。用乙酸乙酯洗涤Celite®:545直至在洗涤物的TLC上看不到化 合物。

[0122]实施例3曲前列素转化为曲前列素二乙醇胺盐(1:1)
[0125] *注:这个重量是基于来自苯并茚三元醇的100%产率。它不是分离产率。曲前列素 保留在前一步骤的乙酸乙酯溶液中并就这样用于这个步骤。
[0126] 林注:乙酸乙酯的总体积应为35L至36L(它应当是所用的乙醇的体积的7倍)。大约 35L乙酸乙酯从前一步骤中保留下来并且添加的1.0L乙酸乙酯被用于冲洗烧瓶。
[0127] 将曲前列素的乙酸乙酯溶液(从前一步骤得到35L至40L)、无水乙醇(5.1L)和二乙 醇胺(435g)装入配有加热/冷却系统、机械搅拌器、冷凝器和热电偶的50-L圆柱形反应器。 搅拌时,将反应混合物加热至60°C至75°C达0.5小时至1.0小时以获得透明溶液。将该透明 溶液冷却至55±5°C。在该温度下,将曲前列素二乙醇胺盐的多晶型物B的晶种(约12g)加至 透明溶液。在该温度下搅拌多晶型物B的悬浮液一小时。将该悬浮液冷却至20±2°C过夜(经 过16小时至24小时)。使用配有滤布的Aurora过滤器通过过滤收集曲前列素二乙醇胺盐并 用乙酸乙酯(2 X8L)洗涤固体。将曲前列素二乙醇胺盐转移至HDPE/玻璃容器中罩内风干, 随后在50 ± 5°C、高真空条件下在真空烘箱中干燥。
[0128]在这个阶段,如果曲前列素二乙醇胺盐的熔点高于104°C,认为它是多晶型物B。不 需要重结晶。如果曲前列素二乙醇胺盐的熔点低于104°C,在EtOH-EtOAc中重结晶曲前列素 二乙醇胺盐以提高熔点。
[0129]曲前列素二乙醇胺盐(1:1)的数据 [0130]
[0131] *注:在这批中,在碳处理之前,大约1200mL曲前列素的乙酸乙酯溶液被取出用于 R&D碳处理实验。
[0132] **注:这批被重结晶,由于这个原因产率较低。
[0133] 实施例4.曲前列素二乙醇胺盐(1:1)的庚烷浆料
[0136] 将曲前列素二乙醇胺盐在庚烷中的浆料(35 L至40 L)装入配有加热/冷却系统、 机械搅拌器、冷凝器和热电偶的50-L圆柱形反应器。将该悬浮液加热至70°C至80°C达16小 时至24小时。将该悬浮液冷却至20 ± 2°C经过1小时至2小时。使用Aurora过滤器通过过滤 收集盐。用庚烷(15 L至30 L)洗涤滤饼并在Aurora过滤器中干燥材料1小时。将该盐转移至 托盘用于罩内风干过夜直至得到恒重的曲前列素二乙醇胺盐。在50°C至55°C、高真空条件 下在烘箱中干燥该材料2小时至4小时。
[0137] 曲前列素二乙醇胺盐(1:1)的分析数据
[0138]
[0139]实施例5.曲前列素二乙醇胺盐(1:1)转化为曲前列素
[0141] 将曲前列素二乙醇胺盐(4g)和水(40mL)装入配有机械搅拌器的250-mL圆底烧瓶。 搅拌混合物以获得透明溶液。将乙酸乙酯(1 〇〇mL)加至透明溶液。在搅拌时,缓慢加入3M HCl(3.2mL)直至达到pH约为1。搅拌混合物10分钟并分离有机层。用乙酸乙酯(2X100mL)萃 取水层。用水(2X 100mL)、盐水(1 X50mL)洗涤合并的有机层并通过无水Na2S〇4干燥所述有 机层。曲前列素的乙酸乙酯溶液被过滤并在50°C、真空下浓缩滤液以得到灰白色固体。曲前 列素粗产物从50%乙醇的水溶液(70mL)中重结晶。通过过滤在Buchner漏斗中收集纯的曲前 列素并且用冷的20%乙醇水溶液洗涤滤饼。将曲前列素的滤饼风干过夜并在50°C、高真空条 件下在真空烘箱中进一步干燥以得到2.9g曲前列素(产率91.4%,纯度(HPLC,AUC)99.8%)。
[0142] 由曲前列素二乙醇胺盐(1:1)生成曲前列素的曲前列素分析数据
[0144] 实施例6.在先方法与根据本发明的方法的实施例的比较
[0145]
[0149] 根据本发明生产的曲前列素的性质优良。省去了通过柱层析纯化苯并茚腈。从中 间步骤(即三元醇的烷基化和苯并茚腈的水解)保留下来的杂质在碳处理和盐形成步骤过 程中除去。该方法额外的优势是:(a)曲前列素盐粗产物可作为原料在室温下保存并可通过 用稀盐酸简单地酸化转化为曲前列素,以及(b)曲前列素盐可从曲前列素的溶液合成而无 需分离。该方法提供更优质的最终产物并且节约大量溶剂和中间体纯化方面的人力。
[0150] 虽然前述内容涉及具体的优选实施方式,但人们理解本发明并不限于此。本领域 技术人员将会想到可对公开的实施方式作出各种修改,并且这些修改应属于本发明的范 围。
