该中间体在本合成路线中的序号：(XVIII)Reductive condensation between aldehyde (XIV) and the piperidine derivative (V) in the presence of NaBH3CN leads to the N-alkylated piperidine (XV). The N-Boc group of (XV) is cleaved under acidic conditions to afford amine (XVI), which is further acylated by 3,5-dichlorobenzoyl chloride (XVII), providing benzamide (XVIII). The oxime O-allyl group of (XVIII) is then removed by treatment with palladium tetrakis(triphenylphosphine) and triethylammonium formate, yielding oxime (XIX). This is subsequently alkylated with bromoacetonitrile and NaH, affording (XX)
