6-Benzyl-3,4-dimeth­oxy-10-methyl­pyrido[2′,1′:2,3]imidazo[4,5-c]isoquinolin-5(6H)-one

摘要

Pyrido[2′,1′:2,3]imidazo[4,5-c]isoquinolin-5(6H)-ones such as the title compound, C24H21N3O3, can be obtained in a few minutes in a microwave-assisted three-component reaction from 2-amino­pyridines, isocyanides and 2-carboxy­benz­aldehydes. In the title compound, the pyrido[2′,1′:2,3]imidazo[4,5-c]isoquinolin-5(6H)-one ring system is almost planar (mean deviation 0.068 Å). The dihedral angle between the benzyl ring and the pyrido[2′,1′:2,3]imidazo[4,5-c]isoquinolin-5(6H)-one ring system is 78.2°. The crystal structure is stabilized by inter­molecular C—H⋯O and C—H⋯N hydrogen bonds.
