実験手順

To a solution of 7-(methylthio)-1H-pyrazolo[4,3-d]pyrimidine (300 mg) and 2-iodoethyl benzoate (548 mg) in N,N-dimethylformamide (10 mL) was added potassium carbonate (374 mg), and the mixture was stirred at 60° C. for 1 hr. After the completion of the reaction, water was added to the reaction mixture. The mixture was diluted with ethyl acetate and washed with water and saturated brine. The organic layer was dried over anhydrous magnesium sulfate, filtered and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (hexane:ethyl acetate=3:2) to give 2-[7-(methylthio)-1H-pyrazolo[4,3-d]pyrimidin-1-yl]ethyl benzoate (266 mg) and 2-[7-(methylthio)-2H-pyrazolo[4,3-d]pyrimidin-2-yl]ethyl benzoate (191 mg) both as pale-yellow solids.
