実験手順
As for Example 11, γ-oxo-2-pyridinebutyric acid, pyridine-1-oxide is coupled to L-proline to give 1-[3-(2-pyridylcarbonyl)propionyl]-L-proline, pyridine-1-oxide. Reaction of the preceding compound with bromine in acetic acid and reaction of the brominated compound with sodium thioacetate in acetonitrile gives the product of the Example as a glass.
