Benzyl 5-phenylpyrazolo[5,1-a]isoquinoline-1-carboxylate
Abstract
In the title compound, C25H18N2O2, the pyrazolo[5,1-a]isoquinoline ring system is approximately planar [maximum deviation = 0.027 (2) Å] and is oriented at dihedral angles of 57.22 (6) and 71.36 (7)° with respect to the two phenyl rings. The phenyl rings are twisted to each other by a dihedral angle of 66.33 (8)°. A weak intramolecular C—H...O hydrogen bond occurs. In the crystal, weak C—H...π interactions are present.
