Bromine → 6-Amino-9-benzyl-8-bromo-2-ethylaminopurine

Participants

Reaction Steps

6-Amino-9-benzyl-2-ethylaminopurine (75 mg, 0.28 mmol) and bromine (0.5 ml) were dissolved in 50 ml of methylene chloride and the solution was stirred at room temperature for 1 hour. Aqueous sodium thiosulfate was added to the reaction mixture. The organic layer was separated, dried on sodium 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 (63 mg, yield 65%).
