## Abstract Intramolecular condensation of the __N__‐(4‐amino‐5‐nitrosopyrimidin‐4‐yl)‐2‐chloroacetamide **2** led to the pteridinone __N(5)__‐oxide **4**, while treatment of **2** with Me~3~P yielded the 8‐(chloromethyl)purine **3**. A high‐yielding [3+2] dipolar cycloaddition of the __N(5)__‐oxid
