Abstract: PROBLEM TO BE SOLVED: To obtain a new 4-phenylpyridine derivative which is a neurokinin 1 receptor antagonist and is useful for pain, headache, Alzheimer's disease, multiple sclerosis, amorphinism relaxation, cardiovascular change, swelling, chronic inflammatory diseases, respiratory diseases, and the like. SOLUTION: A compound of formula I [R is H, a lower alkyl, a lower alkoxy, a halogen or the like; R1 is H or a halogen; R2, R2' are each H, a halogen, trifluoromethyl, a lower alkoxy or cyano, or R and R1, R2 and R2' together form CH=CH-CH=CH which may be substituted by one or more alkyls or the like; R3 is H, a lower alkyl or a cycloalkyl; R4 is H, N(R5)2 (R5 is H, a 3-6C cycloalkyl or the like) or the like; R6 is H, OH, a lower alkyl or the like; X is C(O)N(R5) or the like; (n) is 0-4; (m) is 1 or 2]. For example, N-(3,5-bis-trifluoromethyl-benzyl)-N-methyl-4-o-tolyl-nicotinamide. The compound of formula I is obtained, for example, by reacting a compound of formula II with a compound of formula III.

Abstract: The present invention relates to compounds of the general formula wherein R is hydrogen, lower alkyl, lower alkoxy, halogen or trifluoromethyl; R is hydrogen or halogen; or R and R may be together -CH=CH-CH=CH-; R and R are independently from each other hydrogen, halogen, trifluoromethyl, lower alkoxy or cyano; or R and R may be together -CH=CH-CH=CH-, optionally substituted by one or two substituents selected from lower alkyl or lower alkoxy; R is hydrogen, lower alkyl or form a cycloalkyl group; R is hydrogen, -N(R )2, -N(R )(CH2)nOH, -N(R )S(O)2-lower alkyl, -N(R )S(O)2-phenyl, -N=CH-N(R )2, -N(R )C(O)R or a cyclic tertiary amine of the group R is, independently from each other, hydrogen, C3-6-cycloalkyl, benzyl or lower alkyl; R is hydrogen, hydroxy, lower alkyl, -(CH2)nCOO-lower alkyl, -N(R )CO-lower alkyl, hydroxy-lower alkyl, cyano, -(CH2)nO(CH2)nOH, -CHO or a 5-or 6 membered heterocyclic group, optionally bonded via an alkylene group, X is -C(O)N(R )-, -(CH2)mO-, -(CH2)mN(R )-, -N(R )C(O)-, or -N(R )(CH2)m-; n is 0 - 4; and m is 1 or 2; and to pharmaceutically acceptable acid addition salts thereof. The compounds of formula I show a high affinity to the NK-1 receptor. They may be used for the treatment of diseases, which relate to NK-1 receptor antagonists.
