Reaction Steps

(R)-tert-butyl 3-methyl-1-oxobutan-2-ylcarbamate (2.5 g, 12.42 mmol) was dissolved in THF (50 mL) and cooled to 0° C. Methyl magnesium bromide (17.0 mL, 51.0 mmol, 3.0 M in diethyl ether) was carefully added via syringe. The reaction was allowed to warm to ambient temperature and left stirring overnight. The cloudy mixture was chilled to 0° C., quenched with methanol (3.0 mL, 74.0 mmol), followed by the addition of 200 mL saturated NH4Cl solution, and extracted twice with 200 mL MTBE. The organic phase was washed with 200 mL brine, dried over Na2SO4, filtered, and concentrated to provide the title compound (2.484 g, 11.43 mmol, 92% yield) as a yellow oil. MS (DCI+) m/z 218.1 (M+H).
