Procedure

Crude 6-amino-9-benzyl-8-hydroxy-2-mercaptopurine (200 mg, 0.73 mmol) was suspended in dimethylformamide (80 ml). To the suspension were added potassium carbonate (150 mg, 1.1 mmol) and methyl 3-bromopropionate (0.12 ml, 1.1 mmol) in order. The mixture was stirred at room temperature for 2 hours. The solvent was removed in vacuo, and the residue was purified by silica gel chromatography (3% methanol/chloroform) to give the subject compound (146 mg, yield 56%).
