Reaction Steps

To a solution of lithium carbonate (0.10 g, 1.4 mmol) in DMF (2.5 mL), was added AcOH (0.078 mL, 1.4 mmol) and the solution stirred for a period of 5 min. To this mixture was added a solution of tert-butyl (S)-2-(allyloxy)-1-((S)-oxiran-2-yl)ethylcarbamate (0.11 g, 0.45 mmol) in DMF (2.5 mL). The mixture was heated to 110° C. overnight then cooled to ambient temperature. The cooled mixture was poured onto H2O and 1 N citric acid (20 mL). The aqueous phase was extracted with EtOAc (3×20 mL) and the organic extracts were dried (Na2SO4), filtered, and conc. in vacuo to afford the title compound as a yellow oil. The crude material was used without further purification. MS m/z: 326 (M+23)
