Substituted aminopyrimidines are an important class of compounds, in part because they frequently show biological activity. Facile synthesis of polysubstituted aminopyrimidines is highly desirable for the synthesis of screening libraries. We describe a route to 4,6‐diamino‐5‐alkoxypyrimidines via a SNAr‐alkylation‐SNAr sequence from readily available 4,6‐dichloro‐5‐methoxypyrimidine, which allows the synthesis of such compounds with regiochemical control. Extension of this approach to alkylating agents bearing amino substituents led to unexpected and, in some cases, unprecedented products resulting from intramolecular SNAr cyclisation and subsequent fragmentation.
