Patent number: 6169091
Abstract: Substituted heteroaromatic compounds of formula (A) wherein X is N or CH; in which (a) represents a fused 5, 6 or 7-membered heterocyclic ring and R3 is a group ZR4 wherein Z is joined to R4 through a (CH2)p group in which p is 0, 1, or 2 and Z represents a group V(CH2), V(CF2), (CH2)V, (CF2)V, V(CRR′), V(CHR) or V where R and R′ are each C1-4 alkyl and in which V is a hydrocarbyl group containing 0, 1 or 2 carbon atoms, carbonyl, dicarbonyl, CH(OH), CH(CN), sulphonamide, amide, O, S(O)m or NRb where Rb is hydrogen or Rb is C1-4 alkyl; and R4 is an optionally substituted C3-6 cycloalkyl or an optionally substituted 5, 6, 7, 8, 9 or 10-membered carbocyclic or heterocyclic moiety; or R3 is a group ZR4 in which Z is NRb, and NRb and R4 together form an optionally substituted 5, 6, 7, 8, 9 or 10-membered carbocyclic or heterocyclic moiety, are protein tyrosine kinase inhibitors.
