Reaction Steps

To a suspension of 2-chloro-6-(4-cyclopropyl-2,6-dimethylphenoxy)-9H-purine (28 mg, 0.088 mmol) and 4-aminobenzonitrile (42 mg, 0.35 mmol) in 2,2,2-trifluoroethanol (3 mL) in a sealed tube was added trifluoroacetic acid (0.056 mL, 0.70 mmol). The resulting solution was heated at 90° C. for 3 days. The reaction was cooled to room temperature and concentrated to dryness. Silica gel chromatography (CH2Cl2:Acetone=80:20) yielded 7 mg (20%) of 4-(6-(4-cyclopropyl-2,6-dimethylphenoxy)-9H-purin-2-ylamino)benzonitrile as a light yellow solid.
