Description
技术领域
本发明属于有机合成领域,涉及一种布美他尼(2-磺酰胺基-4-苯氧基-5- 正丁胺基苯甲酸)的合成方法。
技术背景
布美他尼,化学名为2-磺酰胺基-4-苯氧基-5-正丁胺基苯甲酸,为间位氨基苯磺酰胺衍生物,是七十年代丹麦发明的一种起效迅速、作用短暂的强效利尿药。
已有的布美他尼合成路线,大致有如下几种:
专利US3088873、US3985777、DE1966878以对氯苯甲酸为原料进行氯磺化反应、硝化反应、酰胺化反应、醚化反应、硝基还原、氨化反应制备出布美他尼。由于硝化反应时需要在高温85℃下进行,磺酰氯会发生水解反应,该步反应收率较低(文献收率大约60%左右)。在用氨水与氯磺化产物酰胺化过程中,也存在磺酰氯水解反应,考察了浓氨水、氨气,乙腈溶液作为反应介质,收率均不令人满意(文献收率大约50%左右)。此外,在醚化反应时选择性不高,且反应时间较长,大约需要16小时,致使收率偏低。文献报道最后一步氨化反应在正丁醇溶液中硫酸催化氨化,需要60h 才能反应完毕,因此该路线不适合工业化生产。
专利CA1082191以3-磺酰胺基-4-氯-苯甲酸为原料在氯化亚砜中与 DMF反应保护磺酰胺、经过硝化反应、醚化反应、硝基还原、酰胺化反应、硼氢化钠还原酰胺、水解脱去保护基制备出目标产物。反应路线中原料3- 磺酰胺基-4-氯-苯甲酸价格昂贵且不易得到,硝酸化反应属于重点监管的危险工艺,具有潜在爆炸风险,因此该路线也不适合工业化生产。
专利DK134780、CN86108913以3,5-二硝基-4-氯苯甲酸为原料,经过醚化、硝基选择还原,重氮化酰氯化、酰胺化、酯化、还原、丁胺化、水解制备出目标产物,该路线起始原料3,5-二硝基-4-氯苯甲酸价格便宜,避免了硝化潜在的风险。硝基的选择性还原是该路线的难点和关键所在,选择性还原工艺中,保险粉在吡啶体系中进行还原,选择性低收率较低,多数是双还原产物,此外保险粉还原不具备工业化价值,因此该路线不适合工业化生产。
鉴于以上合成工艺存在的弊端,制备布美他尼的清洁、安全工艺依然是本领域技术人员所关注的课题。
