Abstract
Two routes to the antimalarial diaminopyrimidine P218 were developed based on the C-6 metalation of suitable 2,4-dichloro-5-alkoxy pyrimidines using (TMP)2Zn·2MgCl2·2LiCl base. One approach involves a late-stage modification of the C-6 position, while the other allows for tail fragment modification of P218. Both routes have proven reliable in synthesizing P218, as well as eight analogues. These innovative strategies have the potential to contribute to the search for new antimalarial drugs.
