実験手順
1,10-Phenanthroline (0.016 g, 0.087 mmol), cuprous iodide (0.008 g, 0.044 mmol), cesium carbonate (0.21 g, 0.65 mmol), and N-(4-benzyl-2-iodophenyl)-2-fluoro-4-formylbenzamide (0.200 g, 0.44 mmol) were combined under argon. Dioxane (2 mL) was added and the reaction was sealed and heated to 90° C. for 24 h. The reaction was cooled and partitioned between EtOAc and water. The organics were washed with brine, dried over sodium sulfate, filtered, and concentrated. The residue was purified by ISCO, 40 g, 0-30% EtOAc/hexanes to give 4-(6-benzylbenzo[d]oxazol-2-yl)-3-fluorobenzaldehyde as a white solid. MS (ESI) m/z: Calculated: 331.1; Observed: 332.1 (M++1).
