Reaction Steps

To a 150 mL sealable tube was added 4-aminophenol (388 mg, 3.56 mmol), 4-chloro-5-(3,6-dihydro-2H-pyran-4-yl)pyrimidine (700 mg, 3.56 mmol), and cesium carbonate (1218 mg, 3.74 mmol) with DMSO (23.700 ml). The vessel was sealed and heated to 100° C. for 2 h. The reaction mixture was cooled to room temperature and diluted with water before extracting with ethyl acetate. The combined organics were dried over sodium sulfate, filtered, and concentrated under reduced pressure to a dark brown oil that was used without purification. MS (ESI, pos. ion) m/z: 270.0 (M+1).
