실험 절차
A sodium methanol solution (prepared by adding sodium (20 mg, 0.9 mmol) to 1 ml of methanol) was added to a solution of 1-(5-oxohexyl)-3-methyl-7(methylpivaloyl)xanthine (270 mg, 0.7 mmol) in 4 ml of methanol and stirred for 15 min. The reaction mixture was poured into water (20 ml), then extracted with 25% ethanol/dichloromethane (4×50 ml). The organic extracts were combined, dried with sodium sulfate, and evaporated to give a yellow solid. The solid was washed with ether to remove impurities and give CT1505 (1-(5-oxohexyl)-3-methylxanthine) as a white solid (120 mg, 0.45 mmol, 65% yield).
