3-Bromo-1-(3-chloropyridin-2-yl)-N-(4-ethoxyphenyl)-1H-pyrazole-5-carboxamide

Abstract

In the title compound, C17H14BrClN4O2, the pyrazole ring is almost coplanar with the benzene ring [dihedral angle = 0.5 (2)°], whereas the pyrazole ring is close to perpendicular to the 3-chloropyridine ring [dihedral angle = 73.7 (2)°]. An intramolecular C—H...O hydrogen bond occurs. The dominant interaction in the crystal packing is an N—H...N hydrogen bond, which generates a chain along the c axis. Weak intermolecular C—H...O and C—H...N contacts are also observed
