1. A compound of the formula (1b): or a salt thereof, wherein Q is an optionally substituted five or six or seven membered heterocyclic ring containing 1, 2, 3 or 4 heteroatom ring members selected from N, O and S; R3 is selected from hydrogen; fluorine; cyano; hydroxy; amino; and a C1-9 non-aromatic hydrocarbon group which is optionally substituted with one to six fluorine atoms and wherein one, two or three, but not all, carbon atoms of the hydrocarbon group may optionally be replaced by a heteroatom selected from O, N and S and oxidized forms thereof; R4 is a hydrogen or a C1-6 non-aromatic hydrocarbon group which is optionally substituted with one to six fluorine atoms and wherein one or two, but not all, carbon atoms of the hydrocarbon group may optionally be replaced by a heteroatom selected from O, N and S and oxidised forms thereof; and the dotted line indicates an optional second carbon-carbon bond, provided that when a second carbon-carbon bond is present, then R3 is absent.
