실험 절차

With reference to Scheme 4 below, azathalidomide was prepared from aminoglutarimide and commercial pyridine-3,4-dicarboxylic anhydride. Cbz-aminoglutarimide was deprotected by hydrogenolysis with catalyst palladium hydroxide on carbon (10%) to form aminoglutarimide. Pyridine-3,4-dicarboxyic anhydride was refluxed with aminoglutarimide in the presence of triethylamine to yield azathalidomide 11 in the total yield of 17% from Cbz-aminoglutarimide.
