実験手順

Into a 100-mL 3-necked round-bottom flask, was placed 5-amino-3-ethyl-1-phenyl-1H-pyrazole-4-carboxamide (1 g, 4.35 mmol, 1.00 equiv) at room temperature. To the resulting mixture was then added urea (1.75 g, 29.17 mmol, 6.70 equiv), in portions at room temperature. The resulting solution was stirred for 1 h at 200° C. The resulting mixture was then cooled to room temperature. The residue was dissolved in sodium hydroxide (250 mL). The pH value of the solution was adjusted to about 5 with AcOH (conc.). The solids were collected by filtration to yield 3-ethyl-1-phenyl-1H-pyrazolo[3,4-d]pyrimidine-4,6(5H,7H)-dione as a white solid. MS (m/z): 257 [MH+].
