“…The majority of reductions with zinc are carried out in acids: hydrochloric, sulfuric, formic and especially acetic. In previous works, we were interested in the design and synthesis of new molecules that contain a quinolyl moiety (Benzerka et al, 2008;Ladraa et al, 2009, Moussaoui et al, 2002Menasra et al, 2005;Belfaitah et al, 2006, 2007, 2008. In this paper, we report the structure determination of new compound that result from an unwanted reduction of the pyridine ring of 3-cyano-5,8-dimethoxy-2-phenylquinoline.…”
