Versuchsvorschrift

A mixture of 4-bromo-1-((2-(trimethylsilyl)ethoxy)methyl)-1H-benzo[d]imidazole (200 mg, 0.611 mmol), 1-(3,4-dihydroisoquinolin-2(1H)-yl)-3-(3-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)phenoxy)propan-2-ol (375 mg, 0.916 mmol), Pd(dppf)Cl2 (89 mg, 0.12 mmol) and Na2CO3 (130 mg, 1.22 mmol) in dioxane and H2O was stirred under N2 atmosphere at 100° C. for 3 h. The mixture was extracted with DCM and the combined organic layers dried over Na2SO4 and concentrated in vacuum to give the crude product (265 mg, Yield 82%) which was used without further purification.
