실험 절차

1.38 g (5.68 mmol) of 3-nitrophenyl-guanidine nitrate and 0.25 g (6.24 mmol) of sodium hydroxide are added to a solution of 1 g (5.68 mmol) of 3-dimethylamino-1-(4-pyridyl)-2-propen-1-one [U.S. Pat. No. 4,281,000] in 8 ml of isopropanol. The yellow suspension is heated at reflux for 20 hours and then cooled to 0°. After washing with 30 ml of isopropanol the filtration residue is made into a slurry in succession in 15 ml of ethanol and then in 15 ml of water and filtered each time. Drying under HV yields N-(3-nitrophenyl)-4-(4-pyridyl)-2-pyrimidine-amine; m.p. 282°-284°.
