Procedure
6.7 g of tert.-butyl (4S)-1-n-butyl-3-benzyloxycarbonyl-2-oxo-imidazolidine-4-carboxylate, 0.1 g of palladium-black and 200 ml of methanol are treated in the same manner as described in Example 1-(3). 3.8 g of tert.-butyl (4S)-1-n-butyl-2-oxo-imidazolidine-4-carboxylate are obtained as colorless syrup. Yield: 88.1%
