57 The invention provides compounds of the general formula (I)
wherein
X represents a C1-6 alkylene, C2-6 alkenylene or C2-6 alkynylene chain and
Y represents a bond, or a C1-4 alkylene, C2-4 alkenylene of C2-4 alkynylene chain with the proviso that the sum total of carbon atoms in X and Y is not more than 8; Ar represents a phenyl group optionally substituted by one or more substituents selected from halogen atoms, or the groups C1-3 alkyl, C1-3 alkoxy, -(CH2)q OH (where q represents an integer from 0 to 3), - NR3R4 (where R3 and R4 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)-), or -NR5COR6 (where Rs represents a hydrogen atom or a C1-4 alkyl group, and R6 represents a hydrogen atom or a C1-4 alkyl, C1-4 alkoxy, phenyl or -NR3R4 group), or Ar as a phenyl group may be substituted by an alkylenedioxy group of formula -O(CH2)pO-, where p is 1 or 2; R' and R2 each represents a hydrogen atom or a Cl-3 alkyl group, with the proviso that the sum total of carbon atoms in R' and R2 is not more than 4; and physiologically acceptable salts and solvates (e.g. hydrates) thereof.
The compounds of formula (1) have a selective stimulent action at β2-adrenoreceptors and are useful, in particular, in the treatment of diseases associated with reversible airways obstruction such as asthma and chronic bronchitis.
