2-(1,3-Benzodioxol-5-yl)-3-phenyl­quinazolin-4(3H)-one

In the mol­ecule of the title compound, C₂₁H₁₄N₂O₃, the quinazoline ring system [maximum deviation = 0.076 (1) Å] makes dihedral angles of 40.57 (9) and 42.31 (11)°, respectively, with the phenyl and 1,3-benzodioxole rings. The dihedral angle between the phenyl ring and the 1,3-benzodioxole ring is 4.34 (10)°. In the crystal, C—H...O hydrogen bonds link the mol­ecules into infinite zigzag chains extending along [100].

Ethyl 1,4-bis­(4-chloro­phen­yl)-2-methyl-1H-pyrrole-3-carboxyl­ate

In the title mol­ecule, C₂₀H₁₇Cl₂NO₂, the pyrrole moiety makes dihedral angles of 63.42 (11) and 70.43 (12)° with the chlorobenzene rings. The eth­oxy­carbonyl unit is present in a synperiplanar conformation with respect to the pyrrole ring, as indicated by the dihedral angle of 14.5 (3)°. In the crystal, mol­ecules are linked into chains parallel to the a-axis direction by weak C—H...O hydrogen bonds.
