반응 단계

Into a stirred solution of sodium ethoxide (157.7 mg, 2.32 mmol, 2 eq) in EtOH (5.2 ml) was added 5-pyrimidin-5-ylmethyl-2-thioxo-2,3-dihydro-1H-pyrimidin-4-one (270 mg, 1.22 mmol, 1 eq) at rt. After 30 min, the reaction mixture was treated with methyl iodide (190.7 μl, 3.05 mmol, 2.5 eq) and was stirred at rt overnight. Solvent was evaporated and water (1 ml) was added. pH was adjusted ˜4 with 1N HCl and precipitate was formed to give 2-methylsulfanyl-5-pyrimidin-5-ylmethyl-1H-pyrimidin-4-one (196 mg, yield=62.4%, purity=91%). [M+H]+=235.28. 1H NMR (300 MHz; CDCl3) δ/ppm 2.45 (s, 3H), 3.62 (s, 2H), 3.50 (s, 2H), 7.89 (s, 1H), 8.69 (s, 2H), 9.00 (s, 1H)
