6-(4-Chlorophenyl)-2-(4-methoxyphenyl)-6,7-dihydro-4H-pyrazolo[5,1-c][1,4]oxazine
Abstract
In the title compound, C19H17ClN2O2, the pyrazole ring is almost planar with a maximum deviation of 0.009 (3) Å and makes a dihedral angle of 8.96 (9)° with the oxazine ring. The dihedral angles between the pyrazole ring and the chlorine- and methoxy-substituted benzene rings are 50.95 (8) and 13.24 (9)°, respectively. An intermolecular C—H...N hydrogen bond links the molecules into infinite chains along the a axis. The crystal structure is further stabilized by C—H...π interactions.
