Reaktionsschritte

To a solution of 4-aminobenzonitrile (184 mg, 1.56 mmol) in 1-methyl-2-pyrridone (2 mL) was added NaH (62 mg, 1.56 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-phenylsulfanyl)-7H-pyrrolo[2,3-d]pyrimidine (118 mg, 0.31 mmol) in 1-methyl-2-pyrridone (2 mL) was added to the mixture. The mixture was stirred at room temperature for 4 h, then 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 123 mg (83%) of 4-[7-benzyl-4-(2,4,6-trimethyl-phenylsulfanyl)-7H-pyrrolo[2,3-d]pyrimidin-2-ylamino]-benzonitrile.
