2-(Alkylamino)benzonitriles were synthesized via a rhodium-catalyzed cyanation on the aryl C–H bond and subsequent denitrosation of N-nitrosoarylamines using a removable nitroso as the directing group, in which N-cyano-N-phenyl-p-methylbenzenesulfonamide (NCTS) was used as the “CN” source. Various substituents on the aryl ring and amino group of N-nitrosoarylamines tolerated the reaction, and the corresponding

previously utilised in our laboratory for the preparation of the acyclic aryl-guanidine counterparts. Compounds 8b and 18c showed the highest affinity and antagonistic activity, within their series, towards the α2-adrenoceptor in human brain tissue in vitro experiments. Structure-activity relationships have been established for the design and biological evaluation of novel α2-adrenoceptor ligands.
