Ethyl 3-{5-[(diethylamino)methyl]isoxazol-3-yl}-2-phenylpyrazolo[1,5-a]pyridine-5-carboxylate

Abstract

In the title compound, C24H26N4O3, the pyrazolo[1,5-a]pyridine ring system makes dihedral angles of 38.130 (3) and 30.120 (3)°, respectively, with the isoxazole and phenyl rings. In the crystal, two molecules are linked by a pair of C—H...N hydrogen bonds, forming a centrosymmetric dimer. A weak intramolecular C—H...O interaction is also present.
