合成路线1
该中间体在本合成路线中的序号：(IV)Condensation of p-anisidine (I) with 2-oxazolidinone (II) in hot 2-(2-methoxyethoxy)ethanol affords the N-aryl ethanediamine (III). This is then coupled with the succinimidyl ester of N-Z-L-leucine (IV) to furnish amide (V). The N-carbobenzoxy group of (V) is further removed by catalytic hydrogenation, providing amine (VI), which is finally acylated by 4-(benzyloxy)benzoic acid (VII) by means of HATU to yield the title compound.
