Reaction Steps

(4-Fluoro-phenyl)-(2-hydrazino-9-methyl-9H-purin-6-yl)-amine (900 mg, 3.29 mmol) and 2,4-pentanedione (0.47 mL, 4.16 mmol) in ethanol (25 mL) were heated to reflux for 20 min. Water was added and the white crystalline compound was collected by filtration, washed with water and dried to give [2-(3,5-dimethyl-pyrazol-1-yl)-9-methyl-9H-purin-6-yl]-(4-fluoro-phenyl)-amine (1.1 g, 100%).
