The invention relates to compounds of the general formula wherein (R1)n is independently from from each other halogen, lower alkyl or lower alkoxy; R2 is hydrogen, lower alkyl, lower halogen-alkyl, —(CH2)m—OH, —(CH2)m—NR2, —(CH2)mO-lower alkyl, —(CH2)m—C(O)—NR2, or is —(CH2)m-6-membered heteroaryl, optionally substituted by one or more lower alkoxy, —(CH2)m-5 or 6-membered not aromatic heterocyclyl, optionally substituted by hydroxy or lower alkyl; R is hydrogen or lower alkyl and may be the same or different in case of R2; n is 0, 1, or 2; m is 0, 1, 2, 3 or 4; and pharmaceutically acceptable acid addition salts thereof. These compounds have a good affinity to the NK-1 receptor and they are therefore suitable for the treatment of diseases, related to this receptor.
