A compound of formula (I)
where one of A1, A2 or A3 is N, and the others are independently selected from CH or N; ring B is a fused 5 or 6-membered carbocyclic or heterocyclic ring which is optionally substituted as defined in the specification, and R1, R2, R3, R4, and n are as defined in the specification.
The compounds are inhibitors of EphB4 or EphA2 and therefore may be useful in pharmaceutical compositions for the treatment of conditions such as cancer.

The ‘t‐amino effect’ of amino‐nitroso compounds was documented by preparing the (dialkylamino)‐nitroso pyrimidines 4–18, and cyclising them under thermal conditions in high yields to the purine derivatives 19–32. The reactivity of the amino‐nitroso‐pyrimidines, particularly of 17 derived from diethyl iminodiacetate, and of 19, derived from 1‐phenylimidazolidine, correlates with the stability of the
