title: (2SR,3RS)-Benz-yl[4-chloro-1-(4-chloro-phen-yl)-1-methoxy-carbon-yl-2-but-yl]-ammonium chloride.
abstract: In the racemic hydro-chloride salt of the title ester, C(19)H(22)Cl(2)NO(2) (+)·Cl(-), the penta-noic acid chain shows a mixture of trans and gauche orientations to give an overall helical conformation. The dihedral angle between the two aromatic rings is 26.11 (10)°. The charged secondary amine function participates in two N-H⋯Cl hydrogen bonds.
