摘要

A compound of formula (I), wherein R1 and R2 independently are hydrogen, halogen, trifluoromethyl, hydroxy, C1-6-alkyl or C1-6-alkoxy; and R3 is hydrogen or C1-3-alkyl; and A is C1-3-alkylene; and Y is >CH-CH2-,>C=CH-, >CH-O-, >C=N-,>N-CH2- wherein only the underscored atom participates in the ring system, to methods for their preparation, to compositions containing them, and to their use for the clinical treatment of painful, hyperalgesic and/or inflammatory conditions in which C-fibers play a pathophysiological role by eliciting neurogenic pain or inflammation.
