Solvent-free protocol for the green synthesis of benzamide analogs of dibenzoazepine

Dibenzoazepine represents an important class of heterocycles, exhibiting potent antidepressant and anticonvulsant activities. Beside, various modifications on this nucleus, amide analogs at N -5 position showed potent antidepressant activities. A previously reported method for the synthesis of benzamide analogs of dibenzoazepine use hazardous and toxic solvents. Herein, we report a new, efficient and solvent-free green method for the synthesis of dibenzoazepine benzamides (6-21).
