Versuchsvorschrift

A mixture of 3-bromo-1-methyl-1H-pyrrolo[3,2-b]pyridine (200 mg), (4-nitrophenyl)boronic acid (175 mg), Pd(PPh3)4 (95 mg) and Na2CO3 (201 mg) in DME (4 mL) and water (2 mL) was heated at 100° C. for 19 h. After this time, the reaction was cooled to room temperature, diluted with AcOEt (100 mL), washed with water (100 mL) and brine (100 mL), dried over Na2SO4, filtered and the filtrate was concentrated under reduced pressure. The residue obtained was purified by silica gel column chromatography (heptane to 1:1 AcOEt/heptane) to give the title compound (89 mg).
