実験手順

6-Amino-9-benzyl-2-(3-methylbutyl)thiopurine (260 mg, 0.79 mmol) and bromine (0.5 ml) were dissolved in 100 ml of methylene chloride and the solution was stirred at room temperature for 7 hours. Aqueous sodium thiosulfate was added to the reaction mixture. The organic layer was separated, dried on magnesium sulfate and filtered. The solvent in the filtrate was evaporated in vacuo. The residue was purified with silica gel chromatography (1% methanol/chloroform) to give the subject compound (49 mg, yield 15%).
