                            The invention provides compounds of the formula 
wherein
R1 is hydrogen or halogen;
R2 is hydrogen, halogen, lower alkyl or lower alkoxy;
R1 and R2 may together be —CH═CH—CH═CH—, wherein R1 and R2 together with the two carbon ring atoms to which they are attached form a fused ring;
R3 is halogen, trifluoromethyl, lower alkyl or lower alkoxy;
R4/R4′ are each independently hydrogen or lower alkyl;
R5 is lower alkyl, lower alkoxy, amino, phenyl, hydroxy-lower alkyl, cyano-lower alkyl, carbamoyl-lower alkyl, pyridyl, pyrimidyl, —(CH2)n-piperazinyl, which is optionally substituted by one or two lower alkyl groups or by hydroxy-lower alkyl, —(CH2)n-morpholinyl, —(CH2)n-piperidinyl, —(CH2)n+1-imidazolyl, lower alkyl-sulfanyl, lower alkyl-sulfonyl, benzylamino, —NH—(CH2)n+1N(R4″)2, —(CH2)n+1N(R4″)2, —O—(CH2)n+1-morpholinyl, —O—(CH2)n+1-piperidinyl or —O—(CH2)n+1N(R4″)2, wherein R4″ is hydrogen or lower alkyl; and
n is 0-2;
X is —C(O)N(R4″)— or —N(R4″)C(O)—;
and to pharmaceutically acceptable acid addition salts thereof.
It has been shown that the compounds have a good affinity to the NK-1 receptor and may therefore used for the treatment of diseases related to this receptor.
