Conformational aspects of compound 2 have pointed out two factors that determine the conformation of the system under investigation: first, the intermolecular hydrogen bonding of the crystal packing, which stabilizes and favors the occurrence of two independent molecules, and the second factor is the steric hindrance among substituents.
