Coupling between ethyl 3-aminopropionate (I) and N-Boc-glycine (II) by means of EDC and HOBt affords the protected dipeptide (III). After acidic Boc group cleavage in (III), the N-deprotected dipeptide (IV) is acylated by 3,3,3-triphenylpropionic acid (V) to produce amide (VI). Saponification of the ethyl ester group of (VI) yields acid (VII). This is coupled with (R)-1-Boc-3-(aminomethyl)piperidine (VIII) to afford amide (IX), which is further subjected to acidic N-Boc group cleavage. The resultant piperidine derivative (X) is then reductively condensed with cyclohexanecarboxaldehyde (XI) in the presence of NaBH(OAc)3 to furnish the title compound.
