Procedure

A stirred suspension of NaH (63.8 mg, 2.66 mmol) in dry NMP (1.5 mL) was added 4-aminobenzylnitrile (188 mg, 2.66 mmol) and stirred at room temperature for 30 min under argon. The reaction mixture was added to a solution of 5-benzyl-2-fluoro-4-(mesityloxy)-5H-pyrrolo[3,2-d]pyrimidine (115 mg, 0.32 mmol) in dry NMP (1.7 mL) and stirred at room temperature for 2 h. After completion of the reaction, the resulting mixture was diluted with water and washed with EtOAc 3 times. The combined organic layers were washed with water, NH4Cl, water×2, and brine, dried over Na2SO4, filtered, and concentrated in vacuo. The crude product was purified by column chromatography, eluting with 1% MeOH:CH2Cl2, which afforded the product as a tan solid (120 mg, 80%).
