Step D In a manner similar to the method described in Example 1a, glycine tert-butyl ester (1.72 g, 13.2 mmol) was reacted with 2,2-dimethyl-4-oxo-butyric acid benzyl ester (4.1 g, 132 mmol) in CH2Cl2 at room temperature for 18 h to give 4-[(E)-tert-butoxycarbonylmethylimino]-2,2-dimethyl-butyric acid benzyl ester as a colorless oil (4.1 g, 93%).
