実験手順

To a solution of intermediate 238b (1.35 g, 3.12 mmol) in 75 mL of CH2Cl2 at 0° C., was added solid boron trichloride dimethylsulfide complex (2.75 g, 15.3 mmol) all at once. The reaction was stirred overnight, allowing to warm to room temperature. The reaction was quenched by addition to 400 mL of pH 7 phosphate buffer and 200 mL Et2O. After stirring overnight, the aqueous layer was extracted with EtOAc. The combined organic layers were dried (MgSO4), filtered and concentrated. The product was used without further purification. Obtained 680 mg (64%) of an off white solid.
