Reaction Steps

NaH (1.3 g) was added in portions to 70 mL ethanol while cooling. Subsequently D-penicillamine (4.0 g) was added. The mixture kept stirring for 5 minutes at 5° C., after which isopropyl iodide (2.8 mL) was added, The mixture was allowed to stir 16 h at ambient temperature. 2 N HCl was added followed by evaporation of the volatiles to give 11.9 g crude 2-(R)-amino-3-isopropylsulfanyl-3-methyl-butyric acid, which was used in the next step without further purification.
