実験手順

To a solution of 4-chloro-6-(2-furyl)-5H-pyrrolo[3,2-d]pyrimidine (220 mg) in N,N-dimethylformamide (2.5 mL) were added potassium carbonate (139 mg) and methyl iodide (0.25 mL) and the mixture was stirred at room temperature for 8 hrs. The mixture was poured into water (30 mL) and extracted with ethyl acetate (30 mL×3). The organic layers were combined and dried over anhydrous magnesium sulfate. After concentration under reduced pressure, the residue was subjected to silica gel column chromatography (eluent, hexane:ethyl acetate=4:1→0:1) to give the title compound (94 mg).
