Claim:
A compound of formula (I) wherein: Y represents hydrogen or (C 1-6 ) alkyl; Ar represents a phenyl, pyrazolyl or thiazolyl group, wherein the phenyl, pyrazolyl or thiazolyl group is substituted by R 1 and is further optionally substituted; R 1 represents optionally substituted (C 1-6 )alkoxy, halo, optionally substituted(C 1-6 )alkyl, optionally substituted furanyl cyano, or optionally substituted phenyl; R represents an optionally substituted naphthyl, quinolinyl, benzofuranyl or indolinyl group; wherein the optional substituents for said optionally substituted (C 1-6 )alkoxy, (C 1-6 )alkyl, furanyl pyrazolyl, thiazolyl, quinolinyl, benzofuranyl, indolinyl, naphthyl and phenyl are selected from halogen, hydroxy, oxo, cyano, nitro, (C 1-6 )alkyl, (C 1-6 )alkoxy, aryl, halo(C 1-6 )alkyl, halo(C 1-6 )alkoxy, aryl(C 1-6 )alkoxy, (C 1-6 )alkylthio, hydroxy(C 1-6 )alkyl, (C 1-6 )alkoxy(C 1-6 )alkyl, (C 3-6 )cycloalkyl(C 1-6 )alkoxy, (C 1-6 )alkanoyl, (C 1-6 )alkoxycarbonyl, (C 1-6 )alkylsulfonyl, (C 1-6 )alkylsulfonyloxy, (C 1-6 )alkylsulfonyl(C 1-6 )alkyl, arylsulfonyl, arylsulfonyloxy, arylsulfonyl(C 1-6 )alkyl, (C 1-6 )alkylsulfonamido, (C 1-6 )alkylamido, (C 1-6 )alkylsulfonamido(C 1-6 )alkyl, (C 1-6 )alkyl amido(C 1-6 )alkyl, arylsulfonamido, arylcarboxamido, arylsulfonamido(C 1-6 )alkyl, arylcarboxamido(C 1-6 )alkyl, aroyl, aroyl(C 1-6 )alkyl, aryl(C 1-6 )alkanoyl, R 3 R 4 N—, R 3 OCO(CH 2 ) r , R 3 CON(R 4 ) (CH 2 ) r , R 3 R 4 NCO(CH 2 ) r , R 3 R 4 NSO 2 (CH 2 ) r , and R 3 SO 2 NR 4 (CH 2 ) r , wherein each of R 3 and R 4 independently represents a hydrogen atom or a (C 1-6 )alkyl group or R 3 R 4 forms part of a (C 3-6 )azacyloalkane or (C 3-6 )(2-oxo)azacycloalkane ring and r represents zero or an integer from 1 to 4; or a pharmaceutically acceptable salt thereof.
