Procedure

A mixture of glycine tert-butyl ester (Alfa) (2.71 g, 20.0 mmol) and 3,3-dimethyl-butyraldehyde (Alfa) (2.21 g, 21.0 mmol) in CH2Cl2 (50 mL) was stirred at rt overnight. The reaction mixture was concentrated and the residue was dried in vacuo to give [3,3-dimethyl-but-(E)-ylideneamino]-acetic acid tert-butyl ester (4.29 g, 100%) as colorless oil which was used in the next step without further purification.
