The present invention provides a compound of formula (I) wherein R is phenyl, C3-C7 cycloalkyl or heteroaryl, each of which being optionally benzo- or C3-C7 cycloalkyl-fused and optionally substituted, including in the benzo- or C3-C7 cycloalkyl-fused portion, by from 1 to 3 substituents each independently selected from C1-C4 alkyl, fluoro(C1-C4)alkyl, C1-C4 alkoxy, fluoro(C1-C4)alkoxy, phenoxy, C2-C4 alkanoyl, halo, C1-C4 alkoxycarbonyl, C3-C7 cycloalkyl, —S(O)m(C1-C4 alkyl), cyano, —NR2R3, —S(O)mNR2R3, —NR4(C1-C4 alkanoyl) and —CONR2R3, or R is 2,3-dihydrobenzo[b]furanyl or chromanyl; R1 is H or C1-C6 alkyl; W is a direct link, methylene or ethylene; X is unbranched C2-C4 alkylene; Y is phenyl, naphthyl, benzyl, pyridyl, thienyl or C3-C7 cycloalkyl, each of which being optionally substituted by from 1 to 3 substituents each independently selected from C1-C4 alkyl, fluoro(C1-C4)alkyl, C1-C4 alkoxy, fluoro(C1-C4)alkoxy, halo and cyano; Ar is phenyl, naphthyl, benzyl, thienyl, benzo[b]thienyl or indolyl, each of which being optionally substituted by from 1 to 3 substituents each independently selected from C1-C4 alkyl, fluoro(C1-C4)alkyl, C1-C4 alkoxy, fluoro(C1-C4)alkoxy, halo and cyano, or Ar is 1,3-benzodioxolan-4 or 5-yl or 1,4-benzodioxan-5 or 6-yl; ZA is a pharmaceutically acceptable anion; with the proviso that when W is a direct link and R is optionally fused and optionally substituted heteroaryl, said heteroaryl is linked by a ring carbon atom to the carbonyl group. The compounds are tachykinin antagonists.
