There are described compounds of formula (I) wherein R1 and R2 are as defined in the description, Q is heterocyclyl bonded via a ring nitrogen atom and having formula (IA) wherein R3 and R4 and m and n are as defined in the description, the ring marked A is a heterocyclyl having from 5 to 9 ring atoms and having at least one saturated bond, it being possible for a further ring hetero atom selected from O and S to be present in addition to the bonding nitrogen atom, the ring system marked B is a free or benzo-, thieno-, furo-, pyrrolo- or dihydropyrrolo-fused carbocyclic ring having from 5 to 9 carbon atoms that is fused to the ring A and may be unsaturated, partially saturated or fully saturated, and the bond marked by a parallel dotted line between the ring systems marked A and B is either a single bond or a double bond, and a salt thereof where at least one salt-forming group is present. The compounds are inhibitors of protein kinases and have, for example, antitumour activity.
