Versuchsvorschrift
In sealed tube, 180 mg of 6-chloro-4-(1-pyrazolyl)pyrimidine and 2.5 ml of concentrated ammonium hydroxide were warmed at 140° C. for 30 hours. The reaction mixture was dissolved in methylene chloride, and washed with water. The organic fraction was dried over anhydrous sodium sulfute, and distilled off. A residue was recrystallized from methanol to yield 148 mg of 6-amino-4-(1-pyrazolyl)pyrimidine, a flaking crystal having a melting point of 236.5°-237° C.,
