合成路线1
该中间体在本合成路线中的序号：(XVI)Suzuki coupling between 4-bromobenzaldehyde (XII) and 4-trifluoromethylbenzeneboronic acid (XIII) produced the biphenyl compound (XIV). The reductive amination of aldehyde (XIV) with N,N-diethyl ethylenediamine (XV) gave diamine (XVI) (1). This was finally coupled with the intermediate carboxylic acid (XI) to afford the title amide.

合成路线2
该中间体在本合成路线中的序号：(XV)Suzuki coupling between 4-bromobenzaldehyde (XI) and 4-trifluoromethylbenzeneboronic acid (XII) affords the biphenylyl aldehyde (XIII). This is then reductively aminated with N,N-diethylethylenediamine (XIV) and NaBH4 to produce diamine (XV) (1,3). Finally, coupling between amine (XV) and carboxylic acid (VIII) leads to the title carboxamide
