실험 절차
3-Cyano-6-hydroxy-7-oxo-1,7-dihydro-pyrazolo[1,5-a]pyrimidine-5-carboxylic acid methyl ester (100 mg, 0.427 mmol) was suspended in MeOH (10 mL) and to this was added 4-fluorobenzylamine (122 μL, 1.07 mmol) and the reaction was heated at reflux for 2 days before being cooled to room temperature and filtered. The filtrate was concentrated and recrystalised from hot methanol to afford the product a yellow solid (25 mg, 18%).
