Ethyl 3-(4-chloro-phen-yl)-2-(dipentyl-amino)-4-oxo-5-phenyl-4,5-dihydro-3H-pyrrolo-[3,2-d]pyrimidine-7-carboxyl-ate.
In the title compound, C(31)H(37)ClN(4)O(3), the fused rings of the pyrrolo-[3,2-d]pyrimidine system form a dihedral angle of 5.80 (11)°. The phenyl and benzene rings are twisted with respect to the mean plane of the pyrrolo-[3,2-d]pyrimidine system [maximum deviation = 0.077 (2) Å], making dihedral angles of 61.05 (12) and 75.39 (10)°, respectively. The eth-oxy group is disordered over two positions with the site-occupancy ratio fixed at 0.54:0.46. In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds, forming a two-dimensional network lying parallel to the ab plane. There are also π-π [centroid-centroid distances = 3.5954 (17) and 3.965 (2) Å] and C-H⋯π inter-actions present.
