A series of novel 4-subtituted amino-2-methylquinolines (3a-3o) were readily synthesized via the reaction of 4-chloro-2-methylquinoline with amines catalyzed by p-toluenesulfonic acid (TsoH) at 120 degrees C for 1 h under microwave-assisted organic synthesis (MAOS) condition. The yields of products 3a-3o were in range of 55-89%. This approach has advantages such as higher yield, shorter reaction time, lower costs, more convenience, and higher efficiency compared to the conventional method. The structures of the products were characterized by using H-1 NMR, C-13 NMR and HRMS. The reactivity of different amines was discussed.

ligands (MTDLs) to act as multifunctional agents to treat this disease is the mainstream of current research. As a continuation of our previous studies, a series of 4-flexible amino-2-arylethenylquinoline derivatives as multi-target agents was efficiently synthesized and evaluated for the treatment of AD. Among these synthesized derivatives, some compounds exhibited strong self-induced Aβ1⁻42 aggregation
