Reaction Steps
The crystals obtained in step (3), 4.16 g, were dissolved in 40 ml of acetic anhydride and 40 ml of pyridine and stirred at room temperature for 30 minutes. After completion of the reaction, the reaction mixture was concentrated under reduced pressure and the residue was recrystallized from methanol-diethyl ether to provide 4.2 g of 5-(3-acetoxybutyl)-7-hydroxypyrazolo[1,5-a]pyrimidine as colorless crystals.
