实施例
实施例1-合成方法
合成概述
如图1所示,合成VB0004的方法进行了改进。令人惊讶的是,已经发现:如图1所示,开环酸,3-(2-羟基-5-苯基-苯基)丙酸(1495)能够直接由6-溴苯并二氢吡喃-2-酮(1490)的铃木反应来制备。简言之,1495由二氢香豆素以两个步骤合成。通过羧酸的费歇尔酯化,1495被转化成3-(2-羟基-5-苯基-苯基)丙酸乙酯(1496)。3-[5-苯基-2-(三氟甲基磺酰氧基)苯基]丙酸乙酯(1497)的制备包括将1496酚转化成相应的三氟甲磺酸酯。三氟甲磺酸酯是适于铃木偶联和3-[2-(3-羟基-苯基)-5-苯基-苯基]丙酸乙酯(1498)的制备的官能团。1498的碱水解反应然后用于制备3-[2-(3-羟基苯基)-5-苯基-苯基]丙酸(1531)。将1531转化成对应酰胺的最终反应步骤包括使氨气鼓泡通过活化的羧酸的溶液,随后通过沉淀来分离VB0004产物。
合成1490
1490由二氢香豆素合成。
在30分钟内将溴(155ml)在二氯甲烷(500ml)中的溶液加入到3,4-二氢香豆素(450g,0.3摩尔)在二氯甲烷(2000ml)中的溶液中。将混合物在15℃下搅拌过夜,然后用二氯甲烷(2000ml)稀释,并用碳酸氢钠水溶液(2×1000ml)洗涤,然后用水(1000ml)洗涤。溶液用硫酸镁干燥,过滤并减压浓缩。残留物用石油醚(2×500ml)洗涤,浓缩滤液。该固体从二氯甲烷/石油醚中进行重结晶,得到作为厚白色晶体的溴化物(BM1490)(471g,74%)。
合成1495
1495由1490通过铃木反应制备。
在70℃下,将BM1490(140g,0.617摩尔)溶于KOH(69g,1.23摩尔)在水(500mL)中的溶液中。加入苯基硼酸(75.18g,0.617摩尔)在KOH(69g,1.23摩尔)和水(500mL)中的溶液,温度被降至60℃并使其平衡。加入乙酸钯(1.4g),反应在60℃下搅拌过夜。将反应混合物冷却至室温,并用水(300mL)稀释。然后水溶液用甲苯(2×500ml)和汽油(500ml)洗涤。加入冰并且滴加入浓盐酸直至完全酸化。过滤固体。然后将固体溶于EtOAc(1.2L)中并加入活性炭。在环境温度下使混合物搅拌1小时。混合物被过滤、用水(300mL)和盐水(200mL)洗涤,用硫酸镁干燥并浓缩,以得到GC纯度>98%的灰白色固体(110g,74%)。通过1H NMR和UPLC对1495产物的分析表明其具有>99%的纯度,并且通过ICP-MS分析指示,残留的钯含量为3ppm(图2和3)。
合成1496
制备1496的反应是羧酸的费歇尔酯化。反应以定量收率进行而无需纯化1496产物。
将1495(136.5g,563毫摩尔)溶于乙醇(900mL)和浓硫酸(2.2mL)中。反应混合物回流过夜。此后,TLC分析(硅胶板,7:3汽油/乙酸乙酯,UV检测)显示反应完成。反应混合物被冷却到环境温度,添加固体NaHCO3(100g)。将得到的浆液搅拌30分钟。混合物被过滤,用乙醇洗涤并浓缩。粗产物溶解于乙酸乙酯(1L)中,用饱和NaHCO3水溶液(600mL)洗涤,然后加入1M的HCl水溶液(600mL)。有机相用MgSO4(40g)干燥,过滤,用乙酸乙酯洗涤并浓缩,以提供澄清、粘稠的橙棕色液体(152.7g,定量收率)。该物质未经进一步纯化即用于后续步骤。图4示出了1496的1H NMR谱。
合成1497
该步骤包括将1496的酚转化成相应的三氟甲磺酸酯,该三氟甲磺酸酯是适于下一步骤中的铃木偶联的官能团。使用1497而无需进一步纯化。然而,1497可以从甲醇中重结晶以形成低熔点固体。1497在-20℃下储存,且在5个月的时间内没有明显的降解。
将搅拌的1496(150g,553毫摩尔)在二氯甲烷(1.2L)和吡啶(134mL,1.66摩尔)中的溶液冷却至0℃。在0℃下在20分钟内滴加三氟甲磺酸酐(107mL,636毫摩尔),并将得到的混合物升温至环境温度并在环境温度下搅拌过夜。此后,TLC分析(硅胶板,7:3汽油/EtOAc,UV检测)显示反应完成。溶液用二氯甲烷(500mL)稀释并用1M的HCl水溶液(2×600mL)洗涤。然后用二氯甲烷(200mL)萃取含水部分,合并的有机萃取物用水(2×500mL)洗涤。向得到的溶液中加入MgSO4(30g)和活性炭(8g)并搅拌1小时。悬浮液被过滤,用二氯甲烷洗涤并浓缩,以得到橙色油(215g,97%)。中间体1497在未经进一步纯化的条件下使用。图5示出了1497的1H NMR谱。
合成1498和1531
用于制备1498的反应是铃木偶联反应,其将形成VB0004的两个主要组分结合在一起。
随后的1498的碱水解反应提供了作为容易处理的固体的相应的酸。
1498的大规模制造使用四当量的K3PO4碱。后来确定,碱的当量数可以减少到1.5当量,这促进了后处理(work-up),因为反应混合物中不再有显著量的无机固体。最初需要过滤步骤来滤除不溶性固体。该过滤步骤有助于减少已经形成的乳液并且能够分离有机相和水相。碱的当量数减小到1.5当量导致改善很多的后处理且明显降低了乳液的形成。该过滤步骤可能从以下的后处理去除,由于在水溶液后处理期间,在双相混合物中看起来未剩留任何不溶性固体。进行了大量的工作以优化用于1531的纯化的重结晶溶剂。将K3PO4(8.15g,38.4毫摩尔)在水(10mL)中的悬浮液加入到搅拌的1497(10.31g,25.6毫摩尔)和3-羟基苯基硼酸(3.71g,26.9毫摩尔)在四氢呋喃(100mL)中的溶液。在加入钯催化剂([1,1′-双(二苯基膦基)二茂铁]二氯化钯(II)与二氯甲烷的络合物Pd(dppf).Cl2.CH2Cl2,1.0g)之前,反应混合物被加热到80℃。加入催化剂时没有观察到明显的温升。黑色溶液然后在80℃下搅拌过夜,此后TLC分析(硅胶板,4:1,汽油/EtOAc,UV检测)显示反应完成。
将反应混合物浓缩以去除四氢呋喃。加入水(100mL)和乙酸乙酯(100mL),混合物用浓HCl水溶液(20mL)酸化。相被分离,水相用乙酸乙酯(100mL)萃取。将合并的有机萃取物通过玻璃纤维纸过滤(如果需要,例如可用硅藻土代替),然后用盐水(500mL)洗涤。向有机萃取物中加入MgSO4(10g)和活性炭(3g),并将得到的悬浮液搅拌45分钟。混合物被过滤,用乙酸乙酯洗涤并浓缩,以得到粘稠的深棕色油状物。
将NaOH(35.7g,892毫摩尔)在水(600mL)中的溶液加入到搅拌的1498(103g,297毫摩尔)在四氢呋喃(250mL)中的溶液。得到的溶液被加热到60℃持续2小时,此后TLC(硅胶板,1:1的汽油:EtOAc,UV检测)显示反应完成。通过浓缩去除四氢呋喃并将反应混合物用水(400mL)稀释。水相用甲苯(3×500ml)洗涤和用汽油(400ml)洗涤。含水萃取物用HCl处理以使混合物呈酸性。形成的固体被过滤,用水洗涤并干燥以得到粗产物。粗固体从甲苯(400mL)进行重结晶,以得到浅棕色固体1531(40.9g,53%)。该纯化步骤去除了进行该工艺的前期步骤时的许多杂质。1498和1531的1H NMR谱示出于图6和7中,1498的GC结果示出在图8中,1531的UPLC结果示出在图9中。
VB0004的制备
将酸转化成相应的酰胺的最后的反应步骤被证明是具有挑战性的。问题包括酯副产物的形成和最终产物的纯化的困难。本方法包括将氨气鼓泡通过活化的羧酸溶液,随后通过沉淀分离产物。在30分钟内使气体分批鼓泡通过溶液,然后在两次加入氨气之间加热数小时。
随后的甲醇-氨水步骤对于实现完全转化为酰胺是必要的。
在10分钟内,分批将1,1-羰基二咪唑(17.5g,107.9毫摩尔)添加到1531(25g,79.0毫摩尔)在四氢呋喃(250mL)的溶液中。将反应混合物加热至回流并且在氮气下搅拌18小时。此后,将反应混合物冷却至5℃(冰浴),并将氨气鼓入混合物30分钟。在5℃下将氨气反复鼓泡进入混合物持续30分钟之前,反应混合物被加热到回流持续3小时。反应混合物然后被加热至回流过夜。此后,通过减压浓缩来去除四氢呋喃,并添加MeOH(50mL)和25%的氨水溶液(50mL)的混合物。反应混合物被加热到70℃持续2小时。溶液被冷却至环境温度并浓缩至干燥。残留物在1M的HCl水溶液(120mL)中被浆化并过滤。将固体溶于乙酸乙酯(100ml)中,用MgSO4(5g)和活性炭(1g)处理,过滤并浓缩,以得到灰白色的白色固体。该固体通过溶解在乙酸乙酯中,随后通过加入甲苯作为反溶剂使产物沉淀而被纯化。固体被过滤,用甲苯洗涤以及在50℃下的真空炉中干燥,以得到作为白色固体的VB0004产物(17.0g,68%)。在图10中示出了VB0004的1H NMR谱。通过UPLC对产物的分析指示,其具有99.91%的纯度(图11),与参照VB0004材料相比良好的具有99.91%的纯度(图12)。ICP-MS分析表明,VB004含有1ppm的残留钯。
实施例2-可选的合成方法
VB0004也可以通过图13和14所示的方法由二氢香豆素合成。
