2,2 ′ -[2,4-Bis(4-chlorophenyl)cyclobutane-1,3-diyl]bis(8-bromo-6-chloro-3-nitroimidazo[1,2- a ]pyridine).

In the context of our ongoing studies on 3-nitroimidazo[1,2-a]pyridine derivatives as potent antileishmanial compounds, we isolated a new unexpected compound from the spontaneous cycloaddition of N-[2-(8-bromo-6-chloro-3-nitroimidazo[1,2-a]pyridin-2-yl)-1-(4-chlorophenyl)ethyl]-4-methylbenzenesulfonamide. The molecular structure was fully characterized by using 1H and 13C NMR, X-ray crystallography, and HRMS. [ABSTRACT FROM AUTHOR]
