### 5-(4-Chlorophenyl)-7-(4-methylphenyl)-4-(pyrrolidin-1-yl)-7*H*-pyrrolo[2,3-*d*]pyrimidine

**Abstract: **The title compound, C_{23}H_{21}ClN_{4}, contains two molecules (*A* and *B*) in the asymmetric unit, which are related to one another by a pseudo-inversion center. The non-aromatic pyrrolidine ring in each independent molecule adopts a half-chair conformation; the ring puckering parameters are = 0.407 (3) Å and = 270.5 (4)°, and the pseudo-rotation parameters are = 72.5 (3)° and = 42.2 (2)° for an N-C bond of molecule *A*, and the corresponding values are 0.415 (3) Å, 271.6 (4)°, 73.6 (3)° and 42.6 (2)° for molecule *B*. The dihedral angles between the central fused-ring system and the substituted chlorophenyl and methylphenyl rings are 66.35 and 45.59°, respectively, for molecule *A*, and 64.51 and 41.89° for molecule *B*. The geometry of all four intramolecular C-H interactions are of type III. - interactions involving the centroids of symmetry-related pyrrole rings of molecule *B* are 4.390 Å, contributing further to the stability of the molecule.
