PROCEDURE

实验过程

To a solution of 8-chloro-7-(4-chlorobenzyl)-3-((2-(trimethylsilyl)ethoxy)methyl)-1H-purine-2,6(3H,7H)-dione (250 mg, 0.568 mmol) in DMF (30 mL) was added (3-bromopropoxy)(tert-butyl)dimethylsilane (0.2 g, 0.794 mmol), followed by potassium carbonate (160 mg, 1.13 mmol). The mixture was stirred at 70° C. overnight. The reaction was cooled and partitioned between ethyl acetate and water. The combined organic phase was washed with brine, dried over sodium sulfate, and concentrated to give 7-benzyl-1-(3-(tert-butyldimethylsilyloxy)propyl)-8-chloro-3-((2-(trimethylsilyl)ethoxy)methyl)-1H-purine-2,6(3H,7H)-dione (340 mg, 97.4% yield) as colorless oil. LCMS retention time 4.675 min; LCMS MH+ 613.
