Procedure
1M BBr3 in CH2Cl2 (9.5 ml, 9.5 mmol) was added to a solution of the title compound from Step C (0.52 g, 2.78 mmol) in CH2Cl2 (5 mL) at 0° C. The mixture was stirred at 0° C. for 1 h. Water (1 mL) was added. The mixture was extracted with CH2Cl2 (3×10 mL), and dried over Na2SO4. The solvent was removed. The residue was purified by column chromatography on silica gel Biotage 40S, eluting with EtOAc/hexane (3/7) to give the title compound as a colorless gum. 1H NMR (CDCl3, 500 MHz) δ 4.76 (d, J=4.5 Hz, 1H), 3.88 (m, 1H), 2.61 (s, 3H), 2.59 (s, 3H).
