合成路线1
Esterification of N-benzyloxycarbonyl-D-proline (I) with MeOH in the presence of EDC, followed by deprotection of the resultant N-Cbz amino ester (II) with H2 and Pd(OH)2 leads to D-proline methyl ester (III). Subsequent coupling of (III) with N-benzyloxycarbonyl-O-t-butyl-L-4-trans-hydroxyproline (IV) yields the protected dipeptide (V). After removal of the N-benzyloxycarbonyl group of (V) by catalytic hydrogenolysis, the free amine (VI) is acylated by 3,3,3-triphenylpropionic acid (VII), producing amide (VIII). The methyl ester group of (VIII) is then hydrolyzed under alkaline conditions to furnish acid (IX).

合成路线2
Coupling of acid (IX) with (R)-3-(aminomethyl)-1-Boc-piperidine (X) gives the triamide (XI). Deprotection of both N-Boc and O-t-butyl groups of (XI) with trifluoroacetic acid affords (XII). Finally, reductive alkylation of piperidine (XII) with propionaldehyde in the presence of NaBH3CN/ZnCl2 provides the target compound.
