The thiazole ring is planar while the pyrimidine unit fused to it adopts a screw-boat conformation In the crystal, N—H⋯N plus C—H⋯N hydrogen bonds form helical chains along the b-axis direction, which are linked into thick sheets parallel to the bc plane by C—H⋯O hydrogen bonds and π–π interactions between the formamido carbonyl groups and the thiazole rings.
