Reaction Steps

To a solution of azide 12 (120 mg, 0.52 mmol) in acetic acid (2 ml) were successively added anhydrous AcONa (212 mg, 1.9 mmol) and Br2 (0.3 mL, 0.52 mmol). The mixture was stirred at 25° C. for 1 h and then quenched with water (30 mL). The resulting solution was extracted with CH2Cl2 (2×30 mL). The combined organic layers were dried with anhydrous Na2SO4 and concentrated in vacuo. The residue was purified over column chromatography with petroleum ether/EtOAc (9:1 v/v) to give bromo azide 13 (153 mg) as thick liquid.
