Reaktionsschritte

1H-Pyrrolo[3,2-b]pyridine (0.5 g, 4.24 mmol), phenylboronic acid (1.03 g, 8.44 mmol), copper(II) acetate (1.54 g, 8.48 mmol), and 4A molecular sieves (2 g), were suspended in DCM (10 mL). Triethylamine (1.19 mL, 8.5 mmol) and pyridine (0.7 mL, 8.65 mmol) were added and the reaction stirred at r.t. for three days. The reaction mixture was diluted with further DCM, filtered and concentrated in vacuo. Chromatography (silica, EtOAc) gave the title compound (325 mg). δH (CDCl3) 7.80 (1H, d, J 8.2 Hz), 7.54–7.30 (7H, m), 7.15 (1H, brs), 6.88 (1H, brs). LCMS (ES+) RT 1.20 minutes, 195 (M+H)+.
