title: 6-(4-Chloro-phen-yl)-2-(4-meth-oxy-phen-yl)-6,7-dihydro-4H-pyrazolo-[5,1-c][1,4]oxazine.
abstract: In the title compound, C(19)H(17)ClN(2)O(2), 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 meth-oxy-substituted benzene rings are 50.95 (8) and 13.24 (9)°, respectively. An inter-molecular C-H⋯N hydrogen bond links the mol-ecules into infinite chains along the a axis. The crystal structure is further stabilized by C-H⋯π inter-actions.
