In the title compound, C31H37ClN4O3, 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 ethoxy group is disordered over two positions with the site-occupancy ratio fixed at 0.54:0.46. In the crystal, molecules are linked via C—HO 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—Hπ interactions present.
