4-[(E)-(2-Methoxy-phen-yl)imino-meth-yl]-N,N-dimethyl-aniline.

In the title compound, C(16)H(18)N(2)O, the dihedral angle between the benzene rings is 38.5 (2)°. The crystal packing is stabilized by weak C-H⋯N and C-H⋯O inter-actions and aromatic π-π stacking [centroid-centroid separations = 3.620 (5) and 3.546 (4) Å].

1,5-Dimethyl-2-phenyl-4-{[(E)-3,4,5-trimethoxybenzylidene]amino}-1H-pyrazol-3(2H)-one.

In the title compound, C(21)H(23)N(3)O(4), the pyrazole ring forms dihedral angles of 21.58 (8) and 66.64 (7)° with the benzene and phenyl rings, respectively. The crystal structure is stabilized by weak inter-molecular C-H⋯O hydrogen bonds.
