Komponenten

Versuchsvorschrift

A solution of 5-Methoxy-benzofuran-2-boronic acid (1.9 g, 10 mmol), Methyl 4-iodobenzoate (2.61 g, 10 mmol), Pd(Ph3)4 (0.25 g), and 2M NaCO3 (10 ml) in toluene (40 ml) and EtOH (10 ml) was heated to reflux. After 2 hr, the reaction was cooled and the organic layer was seperated dried, and concentrated to give a solid. The solid was triturated with MeOH, filtered to give 127 (0.90 g, 32%) which was used without further purification or characterization for the next step.
