(1R,2R)-2-Benzyloxycarbonylamino-1-phenyl-1,3-propanediol (I) was converted to mesylate (II) upon treatment with methanesulfonyl chloride in pyridine. Reaction of this mesylate with pyrrolidine (III) provided pyrrolidino compound (IV). The N-benzyloxycarbonyl group of (IV) was then eliminated by hydrogenolysis over Pd/C to yield the vicinal hydroxyamine (V), which was finally condensed with decanoyl chloride (VI) to furnish the target decanoyl amide.
