Pesson, Marcel published the artcileAntibacterials. 8-Alkyl-5,8-dihydro-5-oxo-6-pyrido[2,3-d]pyrimidinecarboxylic acids derivatives. III. 2-(4-Arylpiperazinyl)-, 2-(4-aralkylpiperazinyl)-, and 2-(2-imidazolinyl)- derivatives, SDS of cas: 4760-35-4, the publication is European Journal of Medicinal Chemistry (1975), 10(6), 567-72, database is CAplus.
Piperazinylpyridopyrimidinecarboxylic acids I (R = Ph, n = O; R = Ph, 4-ClC6H4, 4-MeOC6H4, 3,4-(MeO)2C6H3, 3,4-methylenedioxyphenyl, 2-furyl, 2-benzimidazolyl, 1-methyl-2-benzimidazolyl, n = 1; R = Ph, PhO, n = 2) were prepared by hydrolyzing the Et esters, obtained by treating the chloropyridopyrimidinecarboxylates with substituted piperazines. II (R1 = Me, Pr, Ph) were obtained by treating the methylsulfonylpyridopyrimidinecarboxylate with 2-imidazolines and hydrolyzing. I (R = Ph, n = 1) had the widest spectrum of bactericidal activity.
