Reaction Steps
A cold (0° C.) solution of tert-butyl 3-(2-methylpropyl)-2-oxo-α-(propen-2-yl)-3-pyrrolidineacetate (1.11 g, 3.76 mmol) in dry THF (25 mL) is treated with NaH (60% dispersion in mineral oil, 226 mg, 5.64 mmol) in one portion. After 30 minutes, benzyl bromide (537 μL, 4.51 mmol) is added. The solution is allowed to slowly warm to room temperature, stirring under N2 overnight. The mixture is quenched with H2O (25 mL) and extracted with EtOAc (3×25 mL). The organic extracts are combined, washed with brine (25 mL), dried over anhydrous Na2SO4, filtered, and concentrated under reduced pressure to yield 1.70 g of yellow oil. The oil is purified by silica gel chromatography (30 g SG, 10% EtOAc/hexane) to give 1.37 g (94%) of the title compound as a clear, colorless oil.
