Abstract
In the title compound {systematic name: (S)-3-[(aminocarbonyl)diphenylmethyl]-1-[2-(2,3-dihydrobenzofuran-5-yl)ethyl]pyrrolidinium bromide}, C28H31N2O2 +·Br−, the pyrrolidine rings adopts an envelope conformation. The two phenyl rings make a dihedral angle of 72.5 (1)°. The four coplanar atoms of the pyrrolidine ring makes dihedral angles of 33.1 (2) and 82.8 (2)° with the two phenyl rings. The molecular conformation is influenced by a C—H⋯O interaction. In the crystal packing, there are two N—H⋯Br hydrogen bonds running in opposite directions. They appear to form C(10) and C(9) chain motifs in the unit cell. In addition, the molecular packing is further stabilized by C—H⋯Br and C—H⋯O hydrogen bonds. The C atom bonded to the benzofuran ring system is disordered in a 0.66:0.34 ratio.
