Abstract
The molecular salt, C 23 H 26 N 2 O 2 + ·Cl − , was obtained from 1-isobutyl-8,9-dimethoxy-3-phenyl-5,6-dihydroimidazo[5,1- a ]isoquinoline, which was synthesized by cyclocondensation of α-benzoylamino-γ-methyl- N -[2-(3,4-dimethoxyphenyl)ethyl]valeramide in the presence of phosphoryl chloride. The tetrahydropyridine ring adopts a twist–boat conformation. In the crystal structure, centrosymmetric dimers are formed by N—H...Cl and C—H...Cl hydrogen bonds.
