Js. Rao et al., SYNTHESIS OF SOME NEW 2-(P-ARYLAZOPHENYL)-1,8-NAPHTHYRIDINES AND THEIR ANTIMICROBIAL ACTIVITY, Indian Journal of Heterocyclic Chemistry, 5(3), 1996, pp. 233-234
A number of 2-(p-arylazophenyl)-1,8-naphthyridines (3) have been synth
esized by the condensation of 2-aminonicotinaldehyde (1) with p-arylaz
oacetophenones (2) in ethanol in the presence of a catalytic amount of
piperidine. The compounds have been tested for their antifungal and a
ntibacterial activities.
