Claim 4:
5. A compound according to claim 1, wherein R1 is selected from 5 or 6 membered heteroaryl, 3 to 9 membered heterocyclyl, or NR7R8; and wherein R1 is optionally substituted by one or more substituent groups selected from fluoro, chloro, trifluoromethyl, trifluoromethoxy, cyano, hydroxy, amino, carboxy, carbamoyl, sulphamoyl, (1-4C)alkyl, (1-4C)alkoxy, S(O)qCH3 (where q is 0, 1, or 2), methylamino, dimethylamino, phenyl, 5 or 6 membered heteroaryl, 3 to 6 membered heterocyclyl, or (3-6C)cycloalkyl,
and wherein any (1-4C)alkyl, (1-4C)alkoxy, phenyl, heteroaryl, heterocyclyl, or (3-6C)cycloalkyl group present within a substituent group on R1 is optionally further substituted by fluoro, chloro, trifluoromethyl, trifluoromethoxy, cyano, nitro, hydroxy, amino, carboxy, carbamoyl, sulphamoyl, (1-4C)alkyl, NRaRb, ORa, C(O)Ra, C(O)ORa, OC(O)Ra, N(Rb)ORa, C(O)N(Rb)Ra, N(Rb)C(O)Ra, S(O)pRa (where p is 0, 1, or 2), SO2N(Rb)Ra, or N(Rb)SO2Ra, wherein Ra and Rb are each independently H or (1-4C)alkyl.
