Potential Antimalarials. X. Di-Mannich Bases of 4-(7'-Trifluoromethyl-1',5'-naphthyridin-4'-ylamino)phenol and N-(4'-Diethylamino-1'-methylbutyl)-7-trifluoromethyl-1,5-naphthyridin-4- amine

Abstract

The syntheses of some di-Mannich bases derived from 4-(7′-trifluoromethyl-1′,5′-naphthyridin-4′-ylamino) phenol and of N-(4′-diethylamino-11′-methylbutyl)-7-trifluoromethyl-1,5-naphthyridin-4- amine from 3-chloro-5-trifluoromethylpyridine via4-chloro-7- trifluoromethyl-1,5-naphthyridine are described. In tests in vitro against the FCQ-27 strain of Plasmodium falciparum these compounds were slightly less active than their 7-bromo analogues.
