Procedure

To a suspension of 2-chloro-4-(4-cyclopropyl-2,6-dimethylphenoxy)-7H-pyrrolo[2,3-d]pyrimidine (75 mg, 0.24 mmol) and 4-aminobenzonitrile (113 mg, 0.96 mmol) in 2,2,2-trifluoroethanol (4 mL) in a sealed tube was added trifluoroacetic acid (0.15 mL, 1.92 mmol). The resulting solution was heated at 90° C. for 3 days. The reaction was diluted with EtOAc (50 mL), washed with NaHCO3 (20 mL) and brine (20 mL), dried with Na2SO4, and concentrated to dryness. Silica gel chromatography (CH2Cl2:Acetone=90:10) yielded 15 mg (16%) of 4-(4-(4-cyclopropyl-2,6-dimethylphenoxy)-7H-pyrrolo[2,3-d]pyrimidin-2-ylamino)benzonitrile as a tan solid.
