4-{[4-(Dimethylamino)benzylidene]­amino}-1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one

The azomethine double-bond in the title Schiff base, C(20)H(22)N(4)O, has an E-configuration. The aromatic ring of the benzyl-idene portion (r.m.s. deviation 0.011 Å) and the five-membered pyrazolyl ring (r.m.s. deviation 0.033 Å) form a dihedral angle of 19.0 (1)°. The phenyl substituent is twisted by 55.0 (1)° with respect to the five-membered ring.

(7-Dimethylamino-1-hydroxy-3-naphthyl)(morpholino)methanone

In the title compound, C(17)H(20)N(2)O(3), the morpholine ring is in a slightly distorted chair form. The crystal structure is stabilized by an inter-molecular O-H⋯O hydrogen bond between the H atom of the hydroxyl group and the O atom of a neighbouring carbonyl group. A weak inter-molecular C-H⋯π inter-action is also present.
