Procedure

0.35 g of 3-nitropyrazolo[1,5-a]pyrimidin-7-ol, 20 cc of acetic acid, 1.6 g of cyclohexene and 85 mg of 10% palladium-on-charcoal were introduced into a 50 cc 3-necked round-bottomed flask fitted with a magnetic stirrer and equipped with a condenser and a thermometer. The medium was refluxed for 1h30' and the catalyst was then filtered off through Celite. After evaporation of the acetic acid, the solid obtained was taken up in 2 cc of refluxing concentrated hydrochloric acid for 2 h 30'. After evaporation of the solvent, an off-white solid was collected.
