実験手順

6-Amino-1-benzyl-5-methylaminouracil (11 g, 43 mmol) was added to a suspension of sodium hydride (1.032 mg, 43 mmol) in anhydrous dimethylsulfoxide (75 ml). After stirring for 30 minutes, (R)-5-acetoxy-1-chlorohexane (7.675 g, 43 mmol) was added. The mixture was heated at 70-80° C. for 12 hours. After cooling to room temperature, the reaction was quenched by the addition of water (150 ml) and extracted with ethyl acetate (3x 125 ml). The combined extracts were washed with water (2x 50 ml), with saturated aqueous sodium chloride solution (50 ml), dried over magnesium sulfate and concentrated under reduced pressure. The residue was purified by flash chromatography on silica gel eluting with ethyl acetate to provide (R)-3-(5-acetoxyhexyl)-6-amino-1-benzyl-5-methylaminouracil (7.89 g).
