nucleophilic sites that are selectively arylated at the CNH2 position are obtained, providing an exceptional tool for rapid delivery of a diverse array of medicinally important CNH(aryl) derivatives of aminoazoles without any protection/deprotection of ring NH bonds. It is first example for the selective CNH2 arylation of 5‐aminoindazole, 4‐aminopyrazole, 5‐aminopyrazole, 9H‐purine‐6‐amine, and 1H‐pyrazolo[3

In this contribution, we report the design, synthesis and cytotoxicity studies of a series of N-[3-(benzimidazol-2-yl-amino)phenyl]amine and N-[3-(benzoxazol-2-ylamino)phenyl]aminederivatives. In vitro cytotoxicity assay of 26 selected compounds was carried out at National Cancer Institute (NCI), USA. Out of them, compounds 10e (NSC D-762842/1) and 11s (NSC D-764942/1) have shown remarkable cytotoxicity
