In a reaction vessel, sodium (21 mg, 0.931 mmol) was dissolved in n-butanol (4 ml) and then 5-(2-fluoro-4-pyridyl)-4,6-di(2-furyl)-2-pyrimidinamine (100 mg, 0.310 mmol) was added thereto, followed by stirring under reflux for 5 hours under an atmosphere of nitrogen gas. The reaction was terminated by adding water thereto. Then, the reaction mixture was extracted with ethyl acetate, washed with water and brine, dried over anhydrous sodium sulfate and then the filtrate was concentrated. The resulting solid was suspended in ethanol, collected by filtration and washed with ethanol, to give the title compound (63 mg, 54%) as a pale yellow solid.
