Trifluoroborane-methyl sulfide → HCID 45483034, compound

Participants

Reaction Steps

Borontrifluoride-dimethylsulfide (0.25 mL, 2.37 mmol) was dropwise added to a solution of the methoxy compound (0.1 g, 0.24 mmol) prepared in Example 37 in dichloromethane (4 mL) at room temperature under nitrogen atmosphere, and stirred for 24 hours. The reaction mixture was concentrated by vacuum distillation. The residue was treated in ethyl acetate (100 mL) and brine (50 mL), and the organic layer was dried over anhydrous magnesium sulfate and distilled under vacuum. Purification through column chromatography (silica gel, ethyl acetate) afforded pure hydroxy products (21 mg, 42%).
