Modification of a series of pyrazole factor Xa inhibitors to incorporate an aminobenzisoxazole as the P1 ligand resulted in compounds with improved selectivity for factor Xa relative to trypsin and plasma kallikrein. Further optimization of the P4 moiety led to compounds with enhanced permeability and reduced protein binding. The SAR and pharmacokinetic profile of this series of compounds is described herein. These efforts culminated in 1-(3′-aminobenzisoxazol-5′-yl)-3-trifluoromethyl-N-[2-fluoro-4- [(2′-dimethylaminomethyl)imidazol-1-yl]phenyl]-1H-pyrazole-5-carboxyamide (11d), a potent, selective, and orally bioavailable inhibitor of factor Xa. On the basis of its excellent in vitro potency and selectivity profile, high free fraction in human plasma, good oral bioavailability, and in vivo efficacy in antithrombotic models, the HCl salt of this compound was selected for clinical development as razaxaban (DPC 906, BMS-561389).

We have discovered an efficient cyanation of aryl chlorides which employs Pd2(dba)3, dppf and Zn as the catalyst and Zn(CN)2 as the cyanide source. Both electron-deficient and electron-rich aryl chlorides are effectively cyanated under these conditions. This discovery represents the first successful palladium-catalyzed cyanation of both electron-deficient and electron-rich aryl chlorides. (C) 2000 DuPont Pharmaceuticals Company.
