Versuchsvorschrift

A mixture of 2-fluoro-4-methanesulfonyl-phenol (Intermediate 1; 66 mg, 0.35 mmol), 4-chloro-1-[4-(3-isopropyl-[1,2,4]oxadiazol-5-yl)-cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidine (Intermediate 23; 60 mg, 0.17 mmol) and potassium carbonate (105 mg, 0.76 mmol) in DMF (1.5 mL) was heated in the microwave at 160° C. for 10 min. Saturated aqueous sodium carbonate solution was added to the cooled reaction mixture. The precipitate was filtered, and the filtrate was extracted with ethyl acetate. The extracts were dried (sodium sulfate), filtered, evaporated, and purified by flash chromatography, eluting with 5% methanol/dichloromethane, to give 4-(2-fluoro-4-methanesulfonyl-phenoxy)-1-[4-(3-isopropyl-[1,2,4]oxadiazol-5-yl)-cyclohexyl]-1H-pyrazolo[3,4-d]pyrimidine (16 mg, 19%) as a white solid. Mass spectrum M+=500.9.
