Abstract

The title compound C₁₅H₁₈N₄O₂ (I), was prepared from the reaction of 4-amino-1-methyl-3-propyl-1H-pyrazole-5- carboxamide and 4-hydroxybenzaldehyde; and was analyzed by analytical data from ¹H NMR, ¹³C NMR, IR and Mass spectra. The crystal structure was determined by single crystal X-ray diffraction. The molecules in the crystal structure form cyclic centrosymmetric supramolecular tetramer synthons [graph-set R44(12)] through amide N-H·O(hydroxy) and hydroxy O-H·O(amide) hydrogen bonds to form perpendicular tapes.
