Condensation of benzodiazepinone (IV) with 4-nitrobenzoyl chloride (V) afforded amide (VI), which was alkylated with ethyl bromoacetate in the presence of NaH to give (VII). The nitro group of (VII) was reduced to aniline (VIII) using Fe and AcOH. Subsequent coupling of (VIII) with the acid chloride generated from biphenyl carboxylic acid (III) and oxalyl chloride produced the corresponding amide (IX). The ester group of (IX) was then hydrolyzed with NaOH, and the resulting carboxylic acid (X) was finally condensed with N-methylpiperazine (XI) using 1-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride and 1-hydroxybenzotriazole as the coupling reagents.
