Reaction Steps
To a suspension of sodium acetate (30.76 g, 375 mmol) in DMF (250 mL) was added dropwise tert-Butyl 2-bromo-acetoacetate (59.27 g, 250 mmol). After stirring at ambient temperature for 90 minutes, water (415 mL) was added, followed by extraction with ethyl acetate (3×325 mL). The combined organic layers were washed with water (3×325 mL) and brine (325 mL), dried over Na2SO4 and after filtration, the solvent was removed in vacuo. The resulting oil was purified by distillation (12 mbar, 128°)
