N-{4-[3-(4-Fluorophenyl)pyrido[2,3-b]pyrazin-2-yl]-2-pyridyl}isopropylamine

Abstract

In the crystal structure of the title compound, C21H18FN5, the pyridopyrazine ring system forms dihedral angles of 33.27 (7) and 48.69 (9)° with the 4-fluorophenyl and pyridine ring, respectively. The dihedral angle of the 4-fluorophenyl and pyridine rings is 57.45 (8)°. The crystal packing is characterized by an intermolecular N—H...N hydrogen bond.
