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.
本发明涉及一般式化合物,其中(R1)n独立地表示卤素、低烷基或低烷氧基;R2表示氢、低烷基、低卤代烷基、—(CH2)m—OH、—(CH2)m—NR2、—(CH2)mO-低烷基、—(CH2)m—C(O)—NR2,或为—(CH2)m-6元杂环芳基,可选择地被一个或多个低烷氧基取代,—(CH2)m-5或6元非芳杂环基,可选择地被羟基或低烷基取代;R表示氢或低烷基,在R2的情况下可能相同或不同;n为0、1或2;m为0、1、2、3或4;以及其药学上可接受的酸盐。这些化合物对NK-1受体有良好的亲和力,因此适用于治疗与该受体相关的疾病。
