n-propylamine, isopropylamine, glycine, morpholine, and piperidine were examined. Highly functionalized Cl2,Cl3,N4,Cl5,Cl6- and N2,Cl3,N4,Cl5,Cl6-substituted pyridines were obtained, in part possessing unsubstituted 4-amino groups due to dealkylation. Detailed NMR studies were performed in order to elucidate the regiochemistry of these dealkylations.
