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

온도

90 °C

To a suspension of (7-benzyl-2-fluoro-7H-pyrrolo[2,3-d]pyrimidin-4-yl)-(2,4,6-trimethyl-phenyl)-amine (42 mg, 0.12 mmol) and 4-aminobenzonitrile (55 mg, 0.47 mmol) in 2,2,2-trifluoroethanol (4 mL) was added trifluoroacetic acid (0.072 mL, 0.94 mmol). The resulting solution was heated at 90° C. for 16 h, then cooled to room temperature. The reaction was concentrated to produce a brown oil and diluted with CH2Cl2 (30 mL). The 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 34 mg (64%) of 4-[7-benzyl-4-(2,4,6-trimethyl-phenylamino)-7H-pyrrolo[2,3-d]pyrimidin-2-ylamino]-benzonitrile.
