الوصف:	In the title compound, C22H17BrN2O4S, the central dihydropyrimidine ring, with a chiral C atom, is significantly puckered and adopts a half-chair conformation with the chiral C atom displaced from the mean plane of the remaining ring atoms by 0.305 (6) Å. The hydroxy-phenyl ring is positioned axially to the pyrimidine ring and almost bisects it, the dihedral angle between the mean-planes of the two rings being 89.78 (12)°. The methoxycarbonyl group is disordered over two sites with an occupancy ratio of 0.568 (5):0.432 (5), resulting in a major and a minor conformer. In the crystal, O—H...N and C—H...S interactions result in sheets along the c axis. The supramolecular assembly is stabilized by π–π stacking interactions between the 2-bromobenzylidene and thiazolopyrimidine rings [centroid–centroid distance = 3.632 (1) Å]. In addition, C—H...π interactions are also observed in the crystal structure.
