3-Aminofuro[2,3-b]pyridines: Reaction with N-Chlorosuccinimide and Sodium Hypochlorite

The reaction of aminoamides of the furo[2,3- b ]pyridine series with an aqueous solution of sodium hypochlorite and N -chlorosuccinimide was studied. It was found that the chlorination reaction proceeds at position 2 of the furopyridine system, leading to previously unknown 3-imino-2-chlorofuro[2,3- b ]pyridine-2-carboxamides. For some synthesized compounds, nucleophilic substitution reactions were investigated. Among the obtained substances, compounds were identified that have antidote activity against 2,4-D.
