| 摘要 |
The present invention relates to a compound represented by the general formula ÄIÜ: <CHEM> wherein A represents a nitrogen atom or a group represented by C-R<5>; Ar<1> represents an aryl group which may have a substituent selected from the group consisting of a halogen atom and lower alkyl and lower haloalkyl groups; Ar<2> represents an aryl or heteroaryl group which may have a substituent selected from the group consisting of a halogen atom and lower alkyl, lower alkenyl, lower haloalkyl, lower alkoxy, lower alkylthio, lower alkylamino, lower dialkylamino and aryl groups; R<1> represents a hydrogen atom, a lower alkyl group or a bond formed by linking to R<5>; R<2> represents a hydrogen atom or a lower alkyl group; R<3> and R<4> may be the same or different and each represents a hydrogen atom or a lower alkyl group, or R<3> and R<4> are linked to each other to form an alkylene group containing 2 to 4 carbon atoms which may have a lower alkyl group; and R<5> represents a hydrogen atom or a hydroxyl, lower alkyl or lower alkoxy group or a bond formed by linking to R<1>, or its salt, a process for its preparation and an agent for the treatment of bulimia, obesity or diabetes comprising it as an active ingredient. |
