Abstract
A rapid synthesis of a series of 6-alkyl substituted-5-(4′-amino-phenyl)-pyrimidine-2,4-diamines is described. These analogs were produced in good yields on moderate scale (ca. 8 g) without chromatography. Furthermore, the methodology described herein allows the production of 6-[ethyl, propyl, isopropyl, and isobutyl]-5-(4′-amino-phenyl)-pyrimidine-2,4-diamines in a more straightforward manner than previously disclosed.Citation[1d] These novel compounds should aid in the structure-activity relationship analysis of current pyrimidines that possess anti-tumor and anti-malarial activities.
