Sodium hydride → 2-chloro-4-(4-cyclopropyl-2,6-dimethylphenoxy)-7H-pyrrolo[2,3-d]pyrimidine

Participants

Reaction Steps

To a solution of 4-cyclopropyl-2,6-dimethylphenol (259 mg, 1.60 mmol) in THF (3 mL) at 0° C. was added NaH (64 mg, 1.60 mmol). The reaction mixture was stirred at room temperature for 30 min and a solution of 2,4-dichloro-7H-pyrrolo[2,3-d]pyrimidine (100 mg, 0.53 mmol) in THF (2 mL) was added to the mixture. The mixture was heated at 80° C. for 16 h and cooled to room temperature. The reaction was poured into ice water and extracted with CHCl3 (3×20 mL). The combined organic solution was washed with H2O (20 mL) and brine (20 mL), dried with Na2SO4, and concentrated to dryness. Silica gel chromatography (Hexanes:EtOAc=75:25) yielded 79 mg (48%) of 2-chloro-4-(4-cyclopropyl-2,6-dimethylphenoxy)-7H-pyrrolo[2,3-d]pyrimidine as a tan solid.
