In the title compound, C20H17N3O4S, all non-H atoms, except those of the phenyl ring, are approximately coplanar [maximum deviation = 0.2214 (1) Å], and the dihedral angle between their best plane and the benzene ring is 53.13 (1)°. A short intramolecular OS contact of 2.838 (1) Å is formed between the ester carbonyl O atom and the S atom of the thiazolidine ring. In the crystal, molecules associated via O—HO, C—HO and C—HS hydrogen bonds form layers parallel to (010), with only C—HO-type short contacts between the molecules in adjacent layers.

In the title compound, C24H20BrN3S, the dihydrothiazole ring is approximately planar, with a maximum deviation of 0.008 (2) Å, and is twisted with respect to the 4-bromophenyl ring, the phenyl ring and methylphenyl ring, making dihedral angles of 47.96 (8), 59.52 (9) and 16.96 (9)°, respectively. In the crystal, weak C—Hπ interactions link inversion-related molecules into supramolecular dimers.
