wherein
Ar represents a phenyl group optionally substituted by one or more substituents selected from halogen atoms, or the groups C1-6 alkyl, nitro, -(CH2)qR, [where R is hydroxy, C1-6 alkoxy. -NR3R4 each represents a hydrogen atom, or a C1-4 alkyl group. or -NR3R4 forms a saturated heterocyclic amino group which has 5-7 ring members and optionally contains in the ring one or more atoms selected from -O- or -S- or a group -NH- or -N(CH3)-), -NR5COR6 (where R5 represents a hydrogen atom or a C1-4 alkyl group, and R6 represents a hydrogen atom or a CI-4 alkyl, CI-4 alkoxy, phenyl or -NR3R4 group), -NR5SO2R (where R7 represents a C1-4 alkyl, phenyl or -NR3R4 group), -COR8 (where R8 represents hydroxy, C1-4alkoxy or -NR3R4, -SR9 (where R9 is a hydrogen atom, or a C1-4 alkyl or phenyl group), -SOR9, -S02R9, or -CN, and q represents an integer from 0 to 3], or -O(CH2)tR11 [where R11 represents a hydroxy or C1-4 alkoxy group and t is 2 or 3], or Ar is a phenyl group substituted by an alkylenedioxy group of formula -O(CH2)pO-, where p represents 1 or 2;
R1 and R2 each represent a hydrogen atom or a CI-3 alkyl group, with the proviso that the sum total of carbon atoms in R1 and R2 is not more than 4;
R30 represents a hydrogen atom or a C1-3 alkyl group; X represents a C2-8 alkylene chain optionally substituted by one or two C1-3 alkyl groups, or, when one carbon atom is substituted by two methyl groups, they may be linked to form an ethylene group, and
Y represents a C1-7 alkylene chain optionally substituted by one or two C1-3 alkyl groups, or, when one carbon atom is substituted by two alkyl groups, they may be linked to form an alkylene group; with the proviso that the sum total of carbon atoms in X and Y is 4 to 12; and with the further proviso that at least one of X and Y is substituted by one or two C1-3 alkyl groups or an alkylene group; Q represents
(where R12 is a straight or branched Ci.3 alkylene group).
(where one or R13 and R14 is a hydroxy group and the other is a hydrogen or halogen atom or a hydroxy group).
[where R'5 is a group R16CO-, R16NHCO-, R16R17NS02- or R18SO2- (where R16 and R17 is each a hydrogen atom or a C1-3 alkyl group and R18 is a C1-3 alkyl group) and p is an integer 0 or 1],
(where R26 and R27 is each a hydrogen atom or a C1-3 alkyl group or, when R26 is a hydrogen atom, R27 may also be a C1-4 alkoxycarbonyl group),

and physiologically acceptable salts and solvates (e.g. hydrates) thereof.
The compounds have a stimulant action at β2-adrenorecep- tors and may be used in the treatment of diseases associated with reversible airways obstruction such as asthma and chronic bronchitis.
