approach towards the production of diverse sets of diaminopyrimidines through sequential SNAr reactions is reported. The readily prepared 2-chloro-4-tetrafluorophenoxypyrymidine reacts regioselectively with amines at the C-2 position. The tetrafluorophenoxy at C-4 can then be replaced with amines in a second SNAr to afford easy access to a different and complementary set of diaminopyrimidines. The broad
