A mixture of 2,4-dioxo-5(1H,3H)-pyrimidinecarbaldehyde (1.79 g, 12.8 mmol), methanol (35 mL) and water (35 mL) was heated at reflux and then a mixture of hydroxylamine hydrochloride (905 mg, 13 mmol), potassium acetate (1.28 g, 13 mmol) and water (15 mL) was added. The mixture was cooled and the solids were collected, washed with water and recrystallized from water/methanol to give 5-hydroxyiminomethyl-2,4(1H,3H)-pyrimidinedione (1.68 g, 10.8 mmol).
