실험 절차

As for Example 1, 3-(5-chloro-2-thenoyl)-2-methylpropionic acid is reacted with L-proline to give 1-[3-(5-chloro-2-thenoyl)-2-methylpropionyl]-L-proline. The mixture of diastereomers is separated. Bromination of [R]-1-[3-(5-chloro-2-thenoyl)-2-methylpropionyl]-L-proline and reaction of the brominated product with sodium thioacetate in acetonitrile gives a mixture of [S-(R*,S*)] and [S-(R*,R*)] isomers of the product of the Example as a glass.
