실험 절차

2-(4-(6-fluoropyridin-2-yl)benzyl)-7-isobutyl-5-methyl-2H-pyrazolo[3,4-d]pyrimidine-4,6(5H,7H)-dione (450 mg, 1.1 mmol) and hexachloroethane (523 mg, 2.2 mmol) are dissolved in 5 mL of methylene chloride, and then 1.0 M LiHMDS (2.2 mL, 2.2 mmol) in THF is added dropwise. After the reaction mixture is stirred at room temperature for 10 min, water is added, and then extracted with methylene chloride three times. The combined organic phase is evaporated to dryness to give 520 mg of crude product as off-white solids, which is used in the next step without further purification. MS (ESI) m/z 442.2 [M+H]+.
