Compounds of formula (I) wherein Y represents a group (CH2)n, wherein n represents 0, 1 or 2; R1 is phenyl, naphthyl, a mono or bicyclic heteroaryl group containing up to 3 heteroatoms selected from N, O and S; or a group NR3R4 wherein one of R?3 and R4¿ is hydrogen or optionally substituted (C¿1-4?)alkyl and the other is phenyl, naphthyl or a mono or bicyclic heteroaryl group containing up to 3 heteroatoms selected from N, O and S, or R?3 and R4¿ together with the N atom to which they are attached form a 5 to 7-membered cyclic amine which has an optionally fused phenyl ring; any of which R1 groups may be optionally substituted; R2 represents phenyl or a 5- or 6-membered hereroaryl group containing up to 3 heteroatoms selected from N, O and S, wherein the phenyl or heteroaryl group is substituted by R5, and further optional substituents; or R2 represents an optionally substituted bicyclic aromatic or bicyclic heteroaromatic group containing up to 3 heteroatoms selected from N, O and S; R5 represents an optionally substituted (C¿1-4?)alkoxy, halo, optionally substituted (C1-6)alkyl, optionally substituted phenyl, or an optionally substituted 5- or 6-membered heterocyclic ring containing up to 3 heteroatoms selected from N, O and S; or pharmaceutically acceptable salts thereof.
