Abstract:The title compound was synthesized from pyridine via N-oxidation,nitration,substitution,ammonolysis,addition-elimination and cyclization. The structure of the target compound was confirmed with IR,1H NMR and MS. Upon optimization of the reaction conditions were obtained:n(4-methoxypyridine 1-oxide) ∶ n(1-tosyl-1H-benzo[d][1,2,3]triazole)=1.5∶1 and the cyclization reaction time 2 h. The process gave the product in overall yield of 35.0% under the optimum conditions. |
Key words:9H-pyrido [2,3-b]indole;synthesis;anticancer |
