    摘要: A muscarinic receptor antagonist, useful in treating irritable bowel syndrome, of the formula:-
    or a pharmaceutically acceptable salt thereof, wherein R¹ is a group of the formula:-
    where Z and Z¹ are each independently hydrogen, halo or C₁-C₄ alkyl;
    X is -(CH₂)₂-, -CH=CH-, -CH₂-S-, -CH₂-O-, -S- or -O-;
    Y is a direct link, O or S;
    R² and R³ are each independently C₁-C₄ alkyl or together represent -(CH₂) p - where p is 2, 3, 4 or 5;
    R⁴ is H or C₁-C₄ alkyl;
    m is 1, 2 or 3, with the proviso that when m is 1, Y is a direct link;
    and R is a group of the formula:-
    where either R⁵ and R⁶ are certain specified optional substituents,
    or R⁵ and R⁶, when attached to adjacent carbon atoms, together represent a group of the formula -O(CH₂) r O- where r is 1, 2 or 3, -O(CH₂)₂- or -(CH₂)₃-;
    R⁷ is H, C₁-C₄ alkyl or -CONH₂;
    and R⁸ is H, C₁-C₄ alkyl or C₁-C₄ alkoxy.
