Reaction Steps
To a solution of 9.36 g (60 mmol) 1,4-cyclohexanedione monoethylene acetal in 60 mL of methanol and 9.84 mL (120 mmol) of propylamine is added 0.6 g of palladium on carbon (10%). The mixture is stirred overnight under 4 bar hydrogen pressure. Filtration over Celite and concentration in vacuum provides the crude product in almost quantitative yield.
