1-(5-Bromo-4-phenyl-1,3-thia­zol-2-yl)pyrrolidin-2-one

The asymmetric unit of the title compound, C(13)H(11)BrN(2)OS, consists of two crystallographically independent mol­ecules (A and B). In each mol­ecule, the pyrrolidine ring adopts an envelope conformation with a methyl­ene C atom as the flap atom. In mol­ecule A, the central thia­zole ring makes a dihedral angle of 36.69 (11)° with the adjacent phenyl ring, whereas the corresponding angle is 36.85 (12)° in mol­ecule B. The pyrrolidine ring is slightly twisted from the thia­zole ring, with C—N—C—N torsion angles of 4.8 (3) and 3.0 (4)° in mol­ecules A and B, respectively. In the crystal, C—H⋯π and π–π [centroid-to-centroid distance = 3.7539 (14) Å] inter­actions are observed. The crystal studied was a pseudo-merohedral twin with twin law (-100 0-10 101) and a refined component ratio of 0.7188 (5):0.2812 (5).
