    • PROBLEM TO BE SOLVED: To provide a muscarinic antagonist which is a piperidine derivative useful for treating cognitive disorders such as Alzheimer's disease.
      SOLUTION: The compound is an amide derivative of a 1,4 di-substituted piperidine compound of formula (I) (wherein R
      1 is an optionally substituted cycloalkyl, cycloalkylalkyl, aryl, arylalkyl or heteroaryl; R
      2 is H, an alkyl or an optionally substituted cycloalkyl, cycloalkylalkyl, heterocycloalkyl, bridged cycloalkyl or bridged heterocycloalkyl; R
      3 is an alkyl or -CH
      2 OH; R
      4 is H or an alkyl; R
      5 is 1-4 substituents each independently chosen from the group consisting of H, an alkyl, a halogen, -OH, an alkoxy, CF
