The synthesis of β3-adrenergicreceptoragonists A and B with radiolabeled amide fragment, required for drug disposition studies, was accomplished based on initial formation of 2-(4-(2-amino-2-methylpropyl)phenoxy)-5-[14C]-cyanopyridine by the reaction of 2-bromo-5-iodopyridine with para-substituted phenol, and following cyanation of aromatic iodide with potassium cyanide-[14C].
