2-bromo-6-isocyanopyridine as novel convertible isocyanide for multicomponent chemistry combines sufficient nucleophilicity with good leaving group capacity of the resulting amide moiety under both basic and acidic conditions. An efficient two-step synthesis of the potent opioid carfentanil demonstrates the practical utility of this reagent.
