Ethyl 4-oxo-1,4-di­hydro­pyridine-3-carboxyl­ate

ABSTRACT: Crystal growth of 3′-carb­oxy-3-methyl-[1,4′-bipyridin]-1-ium chloride in ethanol led to single crystals of ethyl 4-oxo-1,4-di­hydro­pyridine-3-carb­oxy­lic acid, which likely resulted from hydrolysis and esterification of the original compound, and its crystal structure was determined by single-crystal X-ray diffraction. The title compound, C8H9NO3, likely generated through hydrolysis and esterification of 3′-carb­oxy-3-methyl-(1,4′-bipyridin)-1-ium chloride by ethanol, which contained water, has a nearly planar conformation. The crystal structure is sustained by one-dimensional chains along the a-axis direction based on bifurcated N—H⋯(O,O) hydrogen bonds between the NH group of the 4-oxo-1,4-di­hydro­pyridine ring and the two carbonyl O atoms.
