6-Amino-5-(2,2-diethoxy-ethyl)-3H-pyrimidin-4-one (150 mg, 0.7 mmol) was dissolved in 5.0 mL of 1N HCl solution. The mixture was stirred at room temperature for 1 hour and the precipitate was filtered, washed with minimal amount of water and dried in a vacuum oven overnight to give 60 mg (64%) of 3,7-dihydro-pyrrolo[2,3-d]pyrimidin-4-one as a white solid. ¹H NMR (360 MHz, DMSO-d₆)δ 11.83 (s, 1H, NH), 1.75 (s, 1H, NH), 7.80 (s, 1H), 7.01 (dd, J=2.65, 3.21 Hz, 1H), and 6.42 (dd, J=2.09, 3.21 Hz, 1H).
