Reaction Steps

A mixture of 9.6 g of tert.-butyl (4S)-3-benzyloxycarbonyl-2-oxo-imidazolidine-4-carboxylate, 8.3 g of potassium carbonate, 20 g of benzyl bromide and 200 ml of acetone is stirred at room temperature for 3 days. Then, the reaction mixture is treated in the same manner as described in Example 1-(2). 9.3 g of tert.-butyl (4S)-1-benzyl-3-benzyloxycarbonyl-2-oxo-imidazolidine-4-carboxylate are obtained as colorless syrup. Yield: 75.6%
