4-Hydroxybenzoylhydrazine (0.31 g, 2 mmol) and pyruvic acid (0.16 g, 2 mmol) were heated in ethanol (100 ml) for 3 h in an attemp to synthesize a Schiff base. Slow cooling of the filtered solution gave crystals of the hydrazide.
Carbon-bound H-atoms were placed in calculated positions (C–H 0.95 Å) and were included in the
in the riding model approximation, with U(H) set to 1.2U(C). The amino and hydroxy H-atoms were located in a difference Fourier map, and were refined with distance restraints of O–H 0.84±0.01 Å and N–H 0.88±0.01 Å. Their temperature factors were refined.Some 1159 Friedel pairs were merged.
