The azo coupling occurs at the 2 position of the substrate. Different types of intra- and intermolecular non-covalent interactions can affect the supramolecular assembly of the molecules in the crystal structures and the molecular configuration of the synthesized compounds.

In the case of compounds containing the <i>m</i>-chlorophenyl substituent at the C(5) position of the thiazolo[3,2-<i>a</i>]-pyrimidine scaffold, these interactions lead to the formation of halogen-bonded homochiral chains. Due to the π—π stacking between the electron-rich thiazolopyrimidine scaffold and the electron-deficient carboxyphenyl moiety, there occurs the formation of dense layers in the solid phase when selecting the appropriate substituents at the C(5) atom.
