Reaction Steps
L-Leu-OH (10.0 g) was dissolved in water (150 ml) containing concentrated sulfuric acid (3.2 ml) at 0° C. To the solution was added dropwise a solution of sodium nitrate (7.9 g) in water (50 ml) over 1 hour. The mixture was saturated with sodium chloride and extracted with ethyl acetate (500 ml). The organic layer was dried over magnesium sulfate and concentrated in vacuo. The residual solid was triturated with hexane to give (2S)-2-hydroxy-4-methylvaleric acid (6.51 g).
