This compound can be prepared by two related ways: 1) Nitrile (I) was converted to iminoester (II) with methanolic HCl, which was then condensed with (R)-serine methyl ester (III) to give oxazoline (IV). Further reaction of (IV) with O-benzyl hydroxylamine in the presence of AlMe3 provided hydroxamate (VII). Finally, the O-benzyl protecting group was removed by hydrogenolysis over Pd/C. 2) Alternatively, coupling of the benzoic acid (V) with (R)-serine methyl ester (III) produced amide (VI), which was cyclized to the alredy described oxazolidine (IV) with SOCl2.
