Amodiaquine is one of the most active anti-malarial 4-aminoquinoline but its metabolization is believed to generate hepatotoxic derivatives. Previously, we described new analogs of amodiaquine and amopyroquine, in which hydroxyl group was replaced by various amino groups and identified highly potent compounds with lower toxicity. We describe here the synthesis of new analogs that have been modified on their 4'- and 5'-positions in order to reduce their metabolization. A new synthetic strategy was developed using Buchwald coupling reaction as the key step. (C) 2011 Elsevier Masson SAS. All rights reserved.
