Reaction Steps

Triethylamine (1.8 mL, 12.8 mmol), acetic anhydride (1.2 mL, 12.8 mL) and DMAP (10 mg, 0.09 mmol) are subsequentially added to a suspension of 3-amino-3-methyl-butyric acid (1.00 g, 8.5 mmol) in THF (100 mL). After heating at 60° C. for 3 h AcOEt is added and the organic phase is washed with 1N HCl. Drying (Na2SO4), filtration and evaporation of the solvent yields the desired product.
