Reaction Steps

N-(2-Bromo-5-nitrophenyl)-N-(2-methylprop-2-enyl) acetamide (4.5 g, Step B) was dissolved in 50 mL anhydrous DMF, 2.5 g tetraethyl-ammonium chloride, 1.2 g sodium formate, 3 g sodium acetate were added, the resulting mixture was bubbled with nitrogen gas for 10 min. Pd(OAc)2 (350 mg) was added and the mixture was heated at 80° C. under N2 overnight. After the mixture was concentrated in vacuo, it was extracted 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 a yellow gum. MS: 235 (M+1). Calc'd. for C12H14N2O3−234.2.
