© 2022 IUCr.In the title molecule, C23H20Cl2N4O3S, the thiazole ring is planar while the pyrimidine unit fused to it adopts a screw-boat conformation. In the crystal, thick sheets parallel to the bc plane are formed by N-H⋯N, C-H⋯N and C-H⋯O hydrogen bonds together with π-π interactions between the formamido carbonyl groups and the thiazole rings. Hirshfeld surface analysis indicates that the most important contributions to the crystal packing are from H⋯H (30.9%), Cl⋯H/H⋯Cl (20.7%), C⋯H/H⋯C (16.8%) and O⋯H/H⋯O (11.4%) interactions.
