Reaction Steps

2-Chloro-3-(5,6-dihydro-2H-pyran-3-yl)pyrazine (0.13 g, 0.68 mmol), 4-aminophenol (0.15 g, 1.35 mmol), and cesium carbonate (0.44 g, 1.35 mmol) were mixed in DMF (2 mL) in a microwave tube. The tube was sealed and placed under a nitrogen atmosphere. The reaction mixture was stirred at 120° C. for 2.5 h. The reaction mixture was cooled to room temperature and diluted with water. The resulting precipitate was filtered and washed with water to give 4-(3-(5,6-dihydro-2H-pyran-3-yl)pyrazin-2-yloxy)aniline. [M+1]=270.1.
