実験手順
Hydrazine monohydrate (50 ml) was slowly added dropwise to 21.0 g of 5-n-butyl-7-chloropyrazolo[1,5-a]pyrimidine prepared in step (2) of Reference Example 1 at room temperature and stirred at room temperature for 10 hours. After completion of the reaction, the crystals precipitated were collected, washed with water and recrystallized from chloroform-n-hexane to provide 12.6 g of the object compound as colorless crystals (melting point: 126°-129° C.).
