2,4,6-Trimethylphenol → 7-benzyl-4-(2,4,6-trimethyl-phenoxy)-7H-pyrrolo[2,3-d]pyrimidin-2-ylamine

Participants

Reaction Steps

To a solution of 2,4,6-trimethylphenol (161 mg, 1.16 mmol) in 1-methyl-2-pyridone (2 mL) in a sealed tube was added NaH (46 mg, 1.16 mmol). The reaction mixture was stirred at room temperature for 15 min and a solution of 7-benzyl-4-chloro-7H-pyrrolo[2,3-d]pyrimidin-2-ylamine (100 mg, 0.39 mmol) in 1-methyl-2-pyridone (1 mL) was added to the mixture. The mixture was heated at 150° C. for 16 h and cooled to room temperature. The reaction mixture was poured into ice water and extracted with EtOAc (2×20 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 107 mg (77%) of 7-benzyl-4-(2,4,6-trimethyl-phenoxy)-7H-pyrrolo[2,3-d]pyrimidin-2-ylamine.
