実験手順
5,6-Diamino-1-cyclohexylmethyl-2-thioxo-2,3-dihydro-1H-pyrimidin-4-one (1.6 g, 12.2 mmol) was dissolved in ethanol (10 mL) and triethyl orthoformate (10 mL) and the reaction mixture was refluxed for 2.5 h. The solvents were evaporated off and the resulting brown solid was purified by flash chromatography (heptane/ethyl acetate, 4:1-1:1) to give the title compound (110 mg, 9%).
