4-Aminobenzonitrile → 4-[7-benzyl-4-(2,4,6-trimethyl-phenoxy)-7H-pyrrolo[2,3-d]pyrimidin-2-ylamino]-benzonitrile

Participants

Reaction Steps

To a solution of 4-aminobenzonitrile (101 mg, 0.86 mmol) in 1-methyl-2-pyrridone (1 mL) was added NaH (34 mg, 0.86 mmol). The reaction mixture was stirred at room temperature for 15 min and a solution of 7-benzyl-2-fluoro-4-(2,4,6-trimethyl-phenoxy)-7H-pyrrolo[2,3-d]pyrimidine (62 mg, 0.17 mmol) in 1-methyl-2-pyrridone (1 mL) was added to the mixture. The mixture was stirred at room temperature for 1 h, 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 64 mg (82%) of 4-[7-benzyl-4-(2,4,6-trimethyl-phenoxy)-7H-pyrrolo[2,3-d]pyrimidin-2-ylamino]-benzonitrile.
