Compounds of the formula I STR1 wherein X, Y and v are as defined below, novel intermediates used in their synthesis, and the pharmaceutically acceptable salts of such compounds and intermediates. The compounds of formula I and the novel intermediates used in their synthesis are muscarinic receptor antagonists that are selected for smooth muscle muscarinic sites and are useful in the prevention and treatment of diseases associated with altered motility or tone of smooth muscle, such as irritable bowel syndrome, diverticular disease, urinary incontinence, aesophageal achalasia, and chronic obstructive airways disease.

A compound of the formula (IA) or (IB), useful in treating diseases associated with the altered motility and/or tone of smooth muscle, such as irritable bowel syndrome, of the formula:- and their pharmaceutically-acceptable salts, where Y is-CH?CH?-,-CH=CH-,-CH?-S-,-CH?-O-,-O-or-S-; and X is a group of the formula:- wherein m is 1 or 2; R1 and R2 are each independently H or C?-C? alkyl or together represent-(CH?)n-where n is an integer of from 2 to 5; R3 is H or C?-C? alkyl; Z is a direct link,-CH?-,-(CH? )?-,-CH?O-or-CH?S-; and R? is pyridyl, pyrazinyl, thienyl or a group of the formula:- where either R? and R? are each independently selected from H, C?-C? alkyl, C?-C? alkoxy, halo,-CF?,-CN,-(CH?) pNR? R?,-OCO(C?-C? alkyl),-CO(C?-C? alkyl),-CH(OH)(C?-C? alkyl),-C(OH) (C?-C? alkyl)?,-SO?NH?,-NHSO?(C?-C? alkyl),-(CH?)pOH,-(CH?)p COO(C?-C? alkyl),-(CH?)pCONR? R?, or R? and R? together represent-(CH?)q-,-O(CH?) rO-or-O(CH? )t-where in the latter the oxygen atom is attached to the 3-or 4-position of the benzene ring; R? and R? are each independently H or C?-C? alkyl; p is 0, 1 or 2; q is 3, 4 or 5; r is 1, 2 or 3; and t is 2, 3 or 4.
