A significant contaminant of the antimalarial drug piperaquine (1,3-bis-[4-(7-chloroquinolyl-4)-piperazinyl-1]propane) has been identified using liquid chromatography-mass spectrometry (LC-MS) and 2D NMR spectroscopy (1H-1H COSY, 1H-13C HSQC, 1H-13C HMBC). The impurity was identified as the positional isomer 1-[(5-chloroquinolin-4)-piperazinyl]-3-[(7-chloroquinolin-4)-piperazinyl]propane. The impurity is formed

Amodiaquine (AQ) is an antimalarial which is effective against chloroquino-resistant strains of Plasmodium falciparum but whose clinical use is severely restricted because of associated hepatotoxicity and agranulocytosis. "One-pot" synthesis of formamidines likely to be transformed into AQ derivatives is reported.
