Abstract

Sept-Oct 1989 Synthesis of Isomeric Naphthylethylcarbazole Derivatives 1215 yields, respectively, by reacting the methylcarbazoles with benzenesulfonyl chloride using sodium hydride as the condensing agent (Scheme III). Dibromination of 4, S and 6 with 2 moles of NBS in carbon tetrachloride in the presence of benzoyl peroxide as the initiator, the corresponding dibromoethylcarbazoles 7, 8 and 9 were isolated in 85, 82 and 89% yields, ...
