SR 121463 is a potent and selective, orally active vasopressin V2 receptor antagonist. During the synthesis of SR 121463, the formation of the stereochemistry of the cyclohexyl moiety is one of the most important steps. Conformational analysis (via NMR studies and, for cis-3, also via X-ray structure determination) of the isomers obtained in this step is reported.
