Anti-malaria drugs chloroquine and amodiaquine and their metabolites were synthesized to incorporate 13C and 15N starting from U-13C–labeled benzene to give M + 7 isotopomers. Chloroquine and its metabolites were prepared from 7-chloro-1,2,3,4-tetrahydroquinolin-4-one through an aryl substitution with the corresponding amines; and the amodiaquine and its metabolites were prepared from 4,7-dichloroquinoline in a similar fashion.
