To a stirred suspension of NaH (8.9 mg, 0.22 mmol) in dry NMP (1.0 mL) was added 2,4,6-trimethyl phenol (30.2 mg, 0.22 mmol) and stirred at room temperature for 30 min under argon. The reaction mixture was added to a solution of 2,4-dichloro-5-methyl-5H-pyrrolo[3,2-d]pyrimidine (44.6 mg, 0.22 mmol) in dry NMP (1.0 mL) and heated at 90° C. for 16 h. After completion of the reaction, the resulting mixture was cooled, diluted with water and washed with EtOAc. The combined organic layers were washed with water, brine, dried over Na2SO4, filtered, and concentrated in vacuo. The crude product was purified by column chromatography, eluting with hexanes/ethyl acetate (5:1-2:1), to give the product as a light yellow solid (52.7 mg, 80%).
