Reaction Conditions

Reaction Steps

To a solution of 64A (850 mg, 4.6 mmol) in CH2Cl2 (5.0 mL) was added ICl (1.0 M in CH2Cl2, 10.2 mL, 10.2 mmol). The mixture was stirred at 50° C. for 4 h and then at rt for 18 h. The reaction was quenched by a sat. solution of NaHCO3. After extraction with CH2Cl2, the organic layer was washed with a solution of Na2S2O3, brine and dried over Na2SO4. After evaporation of the solvent, the crude product was purified by column chromatography (EtOAc:hexanes=1:4) to give 64B (1.22 g, 80% yield) as a solid. 1H NMR (400 MHz, CDCl3) δ ppm 2.29 (s, 3H) 3.81 (s, 3H) 6.73 (d, J=9.23 Hz, 1H) 7.35 (d, J=6.59 Hz, 1H).
