Reaction Steps

In a sealed tube was added 5-benzyl-2-chloro-4-(2,6-dimethyl-4-nitrophenoxy)-5H-pyrrolo[3,2-d]pyrimidine (598 mg, 1.46 mmol), 4-aminobenzonitrile (691 mg, 5.85 mmol), TFE (9.1 mL) and TFA (1.97 mL, 11.7 mmol). The reaction mixture was stirred at 90° C. for 16 h. Upon completion of the reaction, the resulting mixture was cooled, diluted with water and washed with EtOAc. The combined organic layers were washed with NaHCO3, brine, dried over Na2SO4, filtered, and concentrated in vacuo. The crude product was purified by silica gel column chromatography, eluting with hexanes:ethyl acetate (3:1-1:1), to give the product (442 mg, 60%).
