Reaction Steps
10.4 g of ethyl 4-oxo-4,6,7,8-tetrahydro-pyrrolo[1,2-a]pyrimidine-3-carboxylate are dissolved in 30 ml of 30% by weight of ammonium hydroxide solution. The precipitated crystals are filtered after 2 hours. 8.7 g of 3-carbamoyl-4-oxo-4,6,7,8-tetrahydro-pyrrolo[1,2-a]pyrimidine are obtained with a yield of 96.6%, which melts at 293° C. after recrystallization from dimethyl formamide.
