Reaktionsschritte

31 mg (0.78 mmol) of sodium hydroxide are added to a suspension of 150 mg (0.7 mmol) of 3-dimethylamino-1-(2-chloro-4-pyridyl)-2-propen-1-one and 165 mg (0.71 mmol) of 3-chloro-phenyl-guanidine nitrate in 1.5 ml of 2-propanol. After stirring under reflux for 18 hours, the reaction mixture is cooled and filtered and the material retained on the filter is washed thoroughly with water. After drying (60°, HV), N-(3-chloro-phenyl)-4-(2-chloro-4-pyridyl)-2-pyrimidineamine is obtained; m.p. 196°-198°, Rf =0.67 (methylene chloride:methanol=95:5), FAB-MS: 317 (M+ +1).
