The present invention is directed to a short, facile, effective and industrially applicable process for obtaining 8-chloro-l-methyl-2,3,4,5-tetrahydro-lH- benzo[d]azepine, or its salt, preferably lorcaserin hydrochloride. The present invention is further directed to a simple and effective ring closing methodology for obtaining 8-chloro-l-methyl-2,3,4,5-tetrahydro-lH- benzo[d]azepine, or its salt, preferably lorcaserin hydrochloride. The present invention is also directed to a novel intermediate which can be suitably used in the process for producing 8-chloro-l-methyl-2, 3,4,5- tetrahydro-lH-benzo[d]azepine, or its salt, preferably lorcaserin hydrochloride and to a process for producing the novel intermediate.
