A rapid and efficient one-pot method for the synthesis of 2-(N-substituted)-aminobenzimidazoles is described. The reaction is promoted by dithiocarbamate and catalytic CuO. This procedure is general and can be applied to synthesize many potential drug candidates.
The present invention relates to methods for treating 5-HT
5A
receptor related diseases which comprises administering compounds of formula I
wherein
R
1
, R
2
, aryl, and n are defined in the specification and pharmaceutically acceptable acid addition salts thereof.
