実験手順

Carbon tetrabromide (130 mg) and trimethyl phosphite (46 μL) were added under ice cooling to a solution of the compound of Example 20 (97 mg) in pyridine (0.5 mL) to form a reaction solution. This reaction solution was stirred for 2 hours under ice cooling. Then, water was added to the reaction solution, and the reaction solution was extracted with ethyl acetate. The extract was washed with water and saturated brine in that order, and then dried over anhydrous sodium sulfate. The anhydrous sodium sulfate was removed by filtration, and then the solvent was removed by distillation under reduced pressure. The resultant product was purified by silica gel column chromatography (hexane:ethyl acetate=1:1) to obtain the target product (84 mg) as a colorless oil.
