Reaction Steps

Paudler et al., J. Heterocyclic Chem. 2 (4), 393-8 (1965), show the synthesis and NMR spectra of various 4-substituted-1,6-naphthyridines, for example, the reaction of 4-hydroxy-1,6-naphthyridine with POBr3 or POCl3 to obtain 4-bromo-1,6-naphthyridine or 4-chloro-1,6-naphthyridine, respectively. Also shown is the reaction of 4-bromo-1,6-naphthyridine with dimethylamine to produce 4-dimethylamino-1,6-naphthyridine and the reaction 4-chloro-1,6-naphthyridine with piperidine or hydrazine to produce 4-(1-piperidinyl)-1,6-naphthyridine or 4-hydrazino-1,6-naphthyridine, respectively.
