Abstract

In the title compound, C17H18N4OS, a pyrazoline derivative, the pyrazoline ring adopts an envelope conformation with the C atom bonded to the benzene ring as the flap atom. The dihedral angle between the pyridine and benzene rings is 80.50 (6)°. The eth­oxy­phenyl group is approximately planar, with an r.m.s. deviation of 0.0238 (1) Å for the nine non-H atoms. In the crystal, mol­ecules are linked by N—H⋯O and N—H⋯S hydrogen bonds into a tape along the b axis. Weak C—H⋯N and C—H⋯π inter­actions are also observed
