Reaction Steps
(5-Bromo-2-sulfanylphenyl)methanol (0.50 g, 2.8 mmol) was dissolved in acetonitrile (11.4 mL) followed by the addition of water (11.4 mL) and solid potassium hydroxide (2.56 g, 45.6 mmol). The mixture was plunged into a −78° C. bath and when the mixture began to freeze diethyl [bromo(difluoro)methyl]phosphonate (1.22 g, 4.56 mmol) was added all at once and the cold bath was removed. The mixture was allowed to warm to ambient temperature and was stirred for 20 minutes. The mixture was then partitioned between EtOAc and water. The organic layer was washed with brine, dried over anhydrous MgSO4 and concentrated in vacuo. The residue was purified by MPLC on silica gel (using a gradient elution of 0-25% EtOAc/hexanes). Desired fractions were identified, combined, and concentrated in vacuo to afford the title compound.
