実験手順
In 40 ml of methylene chloride was dissolved 2.5 g of Compound 1 obtained in Example 1, and the solution was cooled to from -5° to -15° C. Then, 20 ml of a hexane solution containing 1M boron tribromide was added thereto. The mixture was stirred at room temperature for two hours and thirty minutes. The reaction mixture was poured into a saturated aqueous sodium bicarbonate solution, followed by extraction with ethyl acetate. The extract was dried over anhydrous magnesium sulfate. The solvent was evaporated under reduced pressure, and the residue was purified by silica gel column chromatography to give 0.63 g of the desired compound as a solid.
