Reaktionsschritte

The compound of step 1 (0.034 g, 0.054 mmol), potassium acetate (0.26 g, 2.7 mmol), 4,4,5,5-tetramethyl-2-(2-(4-nitrophenoxy)phenyl)-1,3,2-dioxaborolane (0.460 g, 1.3 mmol), and 4-chloropyrimidin-2-amine (0.17 g, 1.3 mmol) were combined in a sealed tube under nitrogen, to which 7 nL ACN and water (0.73 ml, 40 mmol) were added. The reaction was sealed and heated to 85° C. overnight. The reaction was diluted with DCM and water, and extracted 2× with DCM. The combined organics were dried over anhydrous sodium sulfate, filtered, and concentrated in vacuo. The resulting material was purified by silica gel chromatography (MeOH/DCM) to give 4-(2-(4-nitrophenoxy)phenyl)pyrimidin-2-amine as a white solid MS m/z=309 [M+H]+. Calc'd for C16H12N4O3: 308.3.
