실험 절차

To a stirred solution of NaH (31 mg, 0.78 mmol) in dry NMP (2 mL) was added 1-(4-hydroxy-3,5-dimethylphenyl)ethanone (127 mg, 0.78 mmol) and stirred at room temperature for 30 min under argon. The reaction mixture was added to a solution of 5-benzyl-2,4-dichloro-5H-pyrrolo[3,2-d]pyrimidine (216 mg, 0.78 mmol) in dry NMP (2.4 mL) and heated at 160° C. for 16 h. After completion of the reaction, the resulting mixture was diluted with water and washed with EtOAc. The combined organic layers were washed with water, 2% NaOH, brine, dried over Na2SO4, filtered, and concentrated in vacuo. The crude product was purified by column chromatography, eluting with hexanes/ethyl acetate (4:1-2:1), to give the product as a light yellow solid (111 mg, 35%).
