Procedure

3-[4-(2-Oxo-3-propyl-6-thioxo-2,3,6,7-tetrahydro-1H-purin-8-yl)-bicyclo[2.2.2]oct-1-yl]-propionic acid methyl ester (100 mg) was dissolved in 2 mL of EtOH and 1 mL of H2O. NaOH (20 mg) was added as a solution in 1 mL of H2O, followed by MeI (23 uL, 1.5 eq). The resulting reaction mixture was stirred at rt for 30 min. It was then extracted with EtOAc. The organic layer was dried (Na2SO4) and concentrated under reduced pressure to afford 105 mg of the titled compound.
