合成路线1
该中间体在本合成路线中的序号：(IV)Coupling between epoxide (I) and amine (II) affords amino alcohol (III). The amino group of (III) is then protected with benzyl chloroformate to provide carbamate (IV). Removal of the N-Boc group of (IV) with trifluoroacetic acid yields amine (V), which is subsequently coupled with N-Boc-L-valine (VI) by means of TBTU to furnish amide (VII). After acidic Boc group cleavage in (VII), the resultant amine (VIII) is acylated by picolinic acid (IX) producing amide (X).
