2-[6-(4-Bromo­phen­yl)imidazo[2,1-b][1,3]thia­zol-3-yl]-N-[8-(4-hy­droxy­phen­yl)-2-methyl-3-oxo-1-thia-4-aza­spiro­[4.5]decan-4-yl]acetamide ethanol disolvate

In the title compound, C(28)H(27)BrN(4)O(3)S(2)·2C(2)H(6)O, the cyclo­hexane ring adopts a chair conformation. The imidazo[2,1-b][1,3]thia­zole ring system is essentially planar with a dihedral angle of 1.1 (2)° between the thia­zole and imidazole rings. The mean plane of this ring system makes dihedral angles of 8.11 (16) and 79.43 (17)°, respectively, with the bromo- and hy­droxy-substituted benzene rings. In the 5-methyl-1,3-thia­zolidin-4-one group, the S atom, the methyl group and the ring C atoms bonded to them are disordered over two sets of sites with refined occupancies of 0.610 (19) and 0.390 (19). The crystal structure features N—H⋯O, O—H⋯O, O—H⋯N and C—H⋯O hydrogen bonds and C—H⋯π inter­actions. Furthermore, two weak π–π stacking inter­actions [centroid–centroid distances = 3.967 (3) and 3.892 (2) Å] are also observed.
