The invention relates to compounds of the formulawhereinR is hydrogen, lower alkyl, lower alkoxy, halogen or trifluoromethyl;R1 is hydrogen or halogen; orR and R1 may be together -CH=CH-CH=CH-;R2 is hydrogen, halogen, trifluoromethyl, lower alkoxy or cyano;R3 is hydrogen, lower alkyl or form a cycloalkyl group;R4 is hydrogen, -N(R5)2, -N(R5)S(O)2-lower alkyl, -N(R5)C(O)R5 or a cyclic tertiary amine of the groupR5 is, independently from each other, hydrogen, C3-6-cycloalkyl, benzyl or lower alkyl;R6 is hydrogen, hydroxy, lower alkyl, -N(R5)CO-lower alkyl, hydroxy-lower alkyl, cyano, -CHO or a 5- or 6 membered heterocyclic group, optionally bonded via an alkylene group,X is -C(O)N(R5)-, -(CH2)mO-, -(CH2)mN(R5)-, -N(R5)C(O)-, or -N(R5)(CH2)m-;n is 0-4; andm is 1 or 2;and to pharmaceutically acceptable acid addition salts thereof.It has been shown that the above mentioned compounds have a good affinity to the NK-1 receptor. |
