Versuchsvorschrift

Combine N-(4-Fluoro-benzyl)-4-[3-(4,4,5,5-tetramethyl-[1,3,2]dioxaborolan-2-yl)-indole-1-sulfonyl]-benzamide (150 mg, 0.28 mmol), 5-Bromo-2-fluoro-pyridine (0.05 mL, 0.56 mmol), CsF (212 mg, 1.4 mmol) and Pd(Ph3P)4 (32 mg, 0.028 mmol) in 1.0 mL DMF and 0.100 mL of water. Evacuate the reaction vessel and place under an atmosphere of nitrogen. Heat the resulting reaction at 90 degrees 12 h. Load the reaction directly onto silica gel and purify by flash column chromatography (EtOAc/Hexanes) to yield 98 mg of white foam (70%) LRMS: MH+ 504.02.
