A compound of formula (I), wherein X represents (CH2)nO, (CH2)nS or C2 alkylene; n represents 1 or 2; Ar<1> represents indanyl, tetrahydronaphthyl, naphthyl or phenyl, which latter two groups may be substituted by one or more substituents selected from chloro, fluoro, OR<1>, O(CH2)mCONR<2O>R<21>, C(O)R<2>, C1-6 alkyl (optionally substituted by one or more fluorine atoms), pyridyl, thiazinyl, phenyl or C7-9 alkylphenyl which latter two groups are optionally substituted by one or more substituent selected from halo, nitro, OR<3>, C1-6alkyl (optionally substituted by one or more fluorine atoms), C(O)R<4>, C(O)OR<5>, C(O)N(R<6>)R<7>, CN, CH2OR<14>, CH2NR<15>R<16>, N(R<8>)R<9>, N(R<10>)SO2R<11>, N(R<12>)C(O)R<13>, OC(O)R<19> and SO2NR<17>R<18>; m represents an integer 1 to 3; R<1>, R<2> and R<3> independently represent H, C1-10 alkyl (optionally substituted by one or more fluorine atoms), C7-9 alkylphenyl or phenyl, which latter group is optionally substituted by hydroxy; and R<4>, R<5>, R<6>, R<7>, R<8>, R<9>, R<10>, R<11>, R<12>, R<13>, R<14>, R<15>, R<16>, R<17>, R<18>, R<19>, R<20> and R<21> independently represent H, C1-6 alkyl (optionally substituted by one or more fluorine atoms) or phenyl; in which any alkyl group represent may be interrupted by one or more oxygen atoms; provided that when X represents CH2CH2, Ar<1> may not represent phenyl or phenyl substituted with one or more substituents OR<1>, in which R<1> represents C1-10 alkyl; or a pharmaceutically acceptable derivative thereof, may be used for the treatment of reversible obstructive airways disease or allergic conditions of the skin, nose and eye.
