6-(Methoxymethyl)pyrimidin-4-ol (948 mg, 6.8 mmole) was taken up in CH2Cl2 (10 mL) and POCl3 (6 mL) at room temperature. After 18 hours, the mixture was concentrated to dryness. The residue was taken up in ice water and the pH adjusted to 7. The mixture was extracted with CHCl3 (4×). The combined organic layers were dried (MgSO4), filtered, and concentrated to give the title compound which was sufficiently pure for use in the next step without purification. 1H-NMR (500 MHz, CDCl3) δ 8.95 (s, 1H), 7.58 (s, 1H), 4.48 (s, 2H), 3.50 (s, 3H).
