Weglinski, Zbigniew; Talik, Tadeusz published an article in 1982, the title of the article was Synthesis of some derivatives of nicotinic acid.Application In Synthesis of Ethyl 5-methyl-6-oxo-1,6-dihydropyridine-3-carboxylate And the article contains the following content:
Hydroxynicotinic acids I (R = 4-Me, 5-Me; R1 = HO) and II (R = 5-Me, 6-Me; R1 = HO) were esterified in EtOH containing H2SO4 to give I and II (R1 = EtO) which were autoclaved with (NH4)2CO3 at 373°K to give I and II (R1 = H2N). Treatment of the Et esters with N2H4 in EtOH gave I and II (R1 = NHNH2). The experimental process involved the reaction of Ethyl 5-methyl-6-oxo-1,6-dihydropyridine-3-carboxylate(cas: 85614-89-7).Application In Synthesis of Ethyl 5-methyl-6-oxo-1,6-dihydropyridine-3-carboxylate
