APPLICATION: DE 75-2517774 18 Apr 1975. DOCUMENT TYPE: Patent CA Section: 27 (Heterocyclic Compounds (One Hetero Atom)) 4-Aminopyridines (I; R, R1 = H, H; H, Me; Me, Me; NRR1 = pyrrolidino, piperidino, morpholino) are prepd. by reaction of 1-(4-pyridinyl)pyridinium chloride-hydrochloride (II) with amides. Thus, reaction of II with DMF 2 hr at 180.degree., followed by treatment overnight with aq. 5421-92-1 and 504-24-5 are just another two chemicals used in this study. NaOH gives 56% I (R, R1 = Me, Me). .
