Abstract: The reaction of 2,3-pyridinediamine 1a and its 5-bromo analogue 1b, independently, with acid chloride or anhydride does not yield the diaroyl derivative and instead yields the cyclised product 3 or the monoaroyl derivative 4 depending upon the conditions. Studies on the attempted condensation of 4 with acid chlorides have been described and a rational explanation has been offered for the unusual resistance of the 2-amino group of 4 towards further attack by electrophiles.
