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.).
