반응 단계

Into a 250-mL round-bottom flask was placed a solution of ethyl 3-amino-1H-pyrrole-2-carboxylate (10 g, 58.38 mmol, 1.00 equiv, 90%) in ethanol (150 mL) and formamidine acetate (10 g, 94.13 mmol, 1.61 equiv, 98%). The resulting solution was stirred at reflux for 16 h. The precipitates were collected by filtration, washed with ethanol and dried under reduced pressure to afford 5 g (61%) of 3H-pyrrolo[3,2-d]pyrimidin-4(5H)-one as a gray solid
