How is N-{4-[(7-Chloro-5-hydroxy-2,3,4,5-tetrahydro-1H-1-benzazepin-1-yl)carbonyl]-3-methylphenyl}-2-methylbenzamide (CAS: 150683-30-0) typically synthesized?

N-{4-[(7-Chloro-5-hydroxy-2,3,4,5-tetrahydro-1H-1-benzazepin-1-yl)carbonyl]-3-methylphenyl}-2-methylbenzamide (CAS: 150683-30-0) is synthesized through a multi-step process involving the condensation of 7-chloro-5-hydroxy-2,3,4,5-tetrahydro-1H-1-benzazepine with 2-methylbenzoic acid. The reaction is typically catalyzed by a mild acid and proceeds with high selectivity and good yield. The key steps include the formation of an intermediate ester, followed by condensation and deprotection.
