  tert-butyl 6-(2'-formylbiphenyl-4-yl)-1-(4-methoxyphenyl)-7-oxo-4,5,6,7-tetrahydro-1H-pyrazolo[3,4-c]pyridin-3-ylcarbamate 、 (R)-3-吡咯烷醇 在 sodium cyanoborohydride 、 zinc(II) chloride 作用下， 以 甲醇 、 四氢呋喃 为溶剂， 反应 24.25h， 以77%的产率得到tert-butyl N-{6-[4-(2-{[(3R)-3-hydroxypyrrolidin-1-yl]methyl}phenyl)phenyl]-1-(4-methoxyphenyl)-7-oxo-1H,4H,5H,6H,7H-pyrazolo[3,4-c]pyridin-3-yl}carbamate

  名称：

  Discovery of 1-(4-Methoxyphenyl)-7-oxo-6-(4-(2-oxopiperidin-1-yl)phenyl)-4,5,6,7-tetrahydro- 1H-pyrazolo[3,4-c]pyridine-3-carboxamide (Apixaban, BMS-562247), a Highly Potent, Selective, Efficacious, and Orally Bioavailable Inhibitor of Blood Coagulation Factor Xa

  摘要：

  Efforts to identify a suitable follow-on compound to razaxaban (compound 4) focused on modification of the carboxamido linker to eliminate potential in vivo hydrolysis to a primary aniline. Cyclization of the carboxamido linker to the novel bicyclic tetrahydropyrazolopyridinone scaffold retained the potent fXa binding activity. Exceptional potency of the series prompted an investigation of the neutral P-1 moieties that resulted in the identification of the p-methoxyphenyl P-1, which retained factor Xa binding affinity and good oral bioavailability. Further optimization of the C-3 pyrazole position and replacement of the terminal P-4 ring with a neutral heterocycle culminated in the discovery of 1-(4-methoxyphenyl)-7-oxo-6-(4-(2-oxopiperidinl-yl)phenyl)-4,5,6,7-tetrahydro-1H-pyrazolo[3,4-c]pyridine-3-carboxamide (apixaban, compound 40). Compound 40 exhibits a high degree of fXa potency, selectivity, and efficacy and has an improved pharmacokinetic profile relative to 4.
