116 °C

A mixture of 2-amino-5-benzyl-3H-pyrrolo[3,2-d]pyrimidin-4(5H)-one (1.1 g, 7.4 mmol) and POCl3 (7 mL, 74 mmol) was heated at 116° C. for 3 h. Upon completion of the reaction, the reaction mixture was poured into ice and extracted three times with ethyl acetate. The combined organic layers were washed with brine, dried over Na2SO4, filtered, and concentrated in vacuo. Purification by column chromatography, eluting with CH2Cl2/Acetone (3:1), afforded the product as a white solid (490 mg, 40%).
