Reaction Steps

Preparation of ethyl-α-N,N-dichloroaminoisobutyrylglycinate: To a solution of 2.16 g (0.01 mol) of ethyl-N-formyl-α-aminoisobutyrylglycinate in 50 ml of dry hydrogen chloride in tetrahydrofuran (1 M), there was added 1 g of 10% palladium-on-charcoal. The mixture was shaken at room temperature under an atmosphere of hydrogen at 50 psi for several days. Following filtration, the solvent was removed under reduced pressure to afford 1.18 g (0.005 mol), 50%, ethyl-α-aminoisobutyrylglycinate hydrochloride, pmr (D2O) δ 4.43 (s, 2H), 4.33 (q, 2H), 1.70 (s, 6H) and 1.23 (t, 3H) ppm.
