Versuchsvorschrift

To a suspension of 2-[4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenoxy]-1H-benzo[d]imidazole (320 mg), 10-bromo-6,7,8,9-tetrahydropyrido[2,3-b]indolizine (217 mg) and K2CO3 (119 mg) in DME (4 mL) and water (1 mL) was added Pd(PPh3)4 (100 mg). The mixture was heated at 150° C. for 40 min under microwave irradiation. The mixture was poured into water and extracted with AcOEt. The organic layer was separated, washed with brine, dried over Na2SO4 and concentrated under reduced pressure. The residue was purified by silica gel column chromatography (AcOEt/hexane) to give the title compound (43.4 mg).
