Three -component reactions involving benzothiazole, isoquinoline and phenanthridine with benzylbromide in the presence of 4-hydroxycoumarine are described. The reactions proceeded smoothly at room temperature without using any catalyst. The structures of the synthesized compounds have been characterized by the spectral studies.

Aza-heterocycles, benzylbromide, 4-Hydroxycoumarine.
