PYRROLOPYRIMIDINE DERIVATIVES FOR TREATING PROLIFERATIVE DISEASES

摘要

The present invention relates to a compound of formula (I), wherein R₁ is a heterocyclic radical or an unsubstituted or substituted aromatic radical; G is C₁-C₇-alkylene, -C(=O)-, or C₁-C₆-alkylene-C(=O)- wherein the carbonyl group is attached to the piperazine moiety; Q is -NH- or -O-, with the proviso that Q is -O- if G is -C(=O)- or C₁-C₆-alkylene-C(=O)-; and X is either not present or C₁-C₇-alkylene, with the proviso that a heterocyclic radical R₁ is bonded via a ring carbon atom if X is not present; or a salt thereof, which is useful for treating anti-proliferative diseases.
