N-(2-Bromo-5-nitrophenyl)-N-(2-methylprop-2-enyl)acetamide (4.5 g, Step B) was dissolved in anhydrous DMF (50 mL), tetraethyl-ammonium chloride (2.5 g), sodium formate (1.2 g), NaOAc (3 g) were added, and the resulting mixture was bubbled with N2 gas for 10 min. Pd(OAc)2 (350 mg) was added and the mixture was heated at 80° C. under N2 atmosphere overnight. After the mixture was concentrated in vacuo, it was partitioned between saturated NaHCO3 solution and EtOAc, the resulting organic layer was dried over MgSO4, filtered and concentrated in vacuo. The crude material was purified by flash chromatography on silica gel with 2:1 Hexane:EtOAc to afford the title compound as a yellow gum. MS: 235 (M+1). Calc'd. for C12H14N2O3—234.25.
