Reaction Steps

To a slurry of freshly prepared silver oxide (filtered/dried from an aqueous mixture of silver nitrate, 0.44 g, 2.70 mmol) and sodium hydroxide (0.21 g, 5.20 mmol)) in 2 mL tetrahydrofuran was added pyrimidin-7(8H)-one (Step A, 0.20 g, 0.52 mmol) and methyl iodide (0.065 mL, 1.04 mmol). After stirring at 50° C. for three days, additional silver oxide and methyl iodide (0.98 mL, 15.7 mmol) were added; the temperature was increased to reflux and the reaction continued for 2 weeks. Following this time period, the mixture was cooled to room temperature, evaporated and purified by column chromatography (SiO2, CH2Cl2/MeOH/NH4OH—90/9/1). Fractions containing product were combined and evaporated under reduced pressure to provide the free amine. This was dissolved in methanol (1-2 mL) and hydrochloric acid in ether (1M, 1.0 eq) was added. Isolation of the solid via filtration, rinsing with ether and drying provided 0.030 g of the hydrochloride salt (Mass spec. M+1=399, MP=135.0-145.0° C.).
