چکیده
With respect to the planar five-membered ring of the title compound, C(16)H(15)N(3)O(2)S, the phenyl ring is aligned at 47.0 (1)° and the phenyl-ene ring at 37.6 (1)°. The amino group has the N atom in a pyramidal geometry; the group is a hydrogen-bond donor to the sulfonyl O atom of one mol-ecule and to the pyrazole N atom of another mol-ecule, resulting in the formation of a layer parallel to the bc plane.
