Synthesis and SAR of N-[4-[(4, 5-dihydropyrazolo [3, 4-d] thieno [3, 2-b] azepin-6 (2H)-yl) carbonyl] phenyl] benzamides as arginine vasopressin (AVP) receptor antagonists are discussed. Potent orally active AVP receptor antagonists are produced when the benzamide moiety contains a phenyl group at the 2-position. Similar analogues of 4, 6, 7, 8-tetrahydro- 5H-thieno [3, 2-b] azepine and VPA-985 are reported.
