ABSTRACT
In the title compound, C14H11ClN2O2S, the dihedral angle between the pyrrolo-[1,2-c]pyrimidine ring system (r.m.s. deviation = 0.008â Å) and the benzene ring is 80.2â (9)°. In the crystal, inversion dimers linked by pairs of C-Hâ¯O inter-actions generate R 2 2(16) loops. Several aromatic π-π stacking inter-actions between the pyrrolo-[1,2-c]pyrimidine rings, as well as separately between the pyrrolo and pyrimidine groups [shortest centroid-centroid separation = 3.5758â (14)â Å], help to consolidate the packing.
