چکیده
In the title compound, C(32)H(33)NO(6)S, the indole ring system makes dihedral angles of 62.78 (10) and 80.53 (8)°, respectively, with the phenyl and benzene rings. In the crystal, the mol-ecules are linked through inter-molecular C-H⋯O hydrogen bonds, forming a chain along the a axis. Between the chains, a weak aromatic π-π stacking inter-action [centroid-centroid distance = 3.831 (2) Å] is observed.

In the title compound, C(15)H(14)O(2)S, the three fused rings are roughly coplanar, the largest deviation from the mean plane being 0.1285 (13) Å for the S atom. An intra-molecular N-H⋯O hydrogen bond generates an S6 ring. In the crystal, inter-molecular C-H⋯O hydrogen bonds form R(2) (2)(14), R(2) (2)(13) and R(3) (2)(17) ring motifs, building a layer parallel to (100).

The title compound, C(20)H(26)N(2)O(5), was prepared in good yield (76%) through condensation of diethyl (4-meth-oxy-benz-yl)propane-dioate with 3,5-dimethyl-1H-pyrazole. The dihedral between the benzene and pyrazole rings is 83.96 (10)°. The crystal packing is stabilized by a C-H⋯O inter-action, which links the mol-ecules into centrosymmetric dimers.
