实验过程

4-(2,6-Dioxo-3-propyl-2,3,6,7-tetrahydro-1H-purin-8-yl)-bicyclo[2.2.2]octane-1-carbaldehyde (900 mg, 2.73 mmol) was dissolved in 25 mL of THF and methyl (triphenylphosphoranylidene)acetate (1.83 g, 2 eq) was added. The resulting reaction mixture was stirred under reflux for 18 h. It was then cooled to rt and purified by preparative HPLC using a mixture of aqueous acetonitrile to afford 300 mg of the desired product.
