N - tert -Butyl-2-{2-[2-(4-chloro-phen-yl)-4-hy-droxy-1-(5-methyl-isoxazol-3-yl)-5-oxo-2,5-di-hydro-1 H -pyrrol-3-yl]- N -(4-meth-oxy-phen-yl)acetamido}-2-(4-meth-oxy-phen-yl)acetamide methanol monosolvate: single-crystal X-ray diffraction study and Hirshfeld surface analysis.

The title compound, C 36 H 37 ClN 4 O 7 ·CH 3 OH, which crystallizes as a methanol solvate, may possess biological activity, which is inherent for a natural peptide or protein. In the crystal, mol-ecules of the title compound form hydrogen-bonded tetra-mers with the solvate mol-ecules acting as bridges as a result of the O-H⋯O and N-H⋯O inter-molecular hydrogen bonds. Hirshfeld surface analysis was used to study the different types of inter-molecular inter-actions whose contributions are: H⋯H = 53.8%, O⋯H/H⋯O = 19.0%, C⋯H/H⋯C = 14.8%, Cl⋯H/H⋯Cl = 5.3%, N⋯H/H⋯N = 3.2%.
