合成路线1
该中间体在本合成路线中的序号：(III)N-tert-Butoxycarbonyl valine (I) was converted to amide (III) by coupling with pyrrolidine (II) by means of DCC and HOBT. Simultaneous reduction of both carbamoyl and amide functions of (III) using excess LiAlH4 in THF gave the chiral diamine (IV). Final acylation of (IV) with (3,4-dichlorophenyl)acetyl chloride (V) in CH2Cl2 yielded the target amide.
