A solution of sodium chlorite (0.348 g, 3.84 mmol) and sodium dihydrogenphosphate monohydrate (0.318 g, 2.306 mmol) in water (4 mL) was added to a solution of bis(1,1-dimethylethyl)(4-bromo-5-formyl-1H-imidazol-2-yl)imidodicarbonate (0.150 g, 0.384 mmol), 2-methyl-2-butene (2M in THF) (2.402 mL, 4.80 mmol), t-BuOH (2 mL) and THF (6 mL). The mixture was stirred at RT overnight and extracted with EtOAc. The organic layer was dried over sodium sulfate and concentrated. The residue was triturated with ether to give the desired product (0.047 g, 30%) as a white solid. ES MS: m/z 406 (M+1).
