Reaction Steps
A mixture of (S)-tert-butyl 1-amino-4-methyl-1-oxopentan-2-ylcarbamate (1.8 g, 8 mmol) and Lawesson's reagent (1.58 g, 4 mmol) in toluene (20 mL) was stirred at 90° C. for 2.5 h. After removal of the solvent under reduced pressure, the residue was purified by column chromatography (silica gel, 30 g, ethyl acetate/MeOH, 20/1) to yield the title compound (1.38 g, 72%) as yellow solid; MS: m/e 269.2 [M+H]+.
