実験手順

A mixture of tert-butyl 2-[3-[bis(tert-butoxycarbonyl)amino]-6-bromo-pyrazin-2-yl]benzimidazole-1-carboxylate (100 mg, 0.1694 mmol), 1-phenyl-4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)-3,6-dihydro-2H-pyridine (58 mg, 0.2034 mmol), 4-ditert-butylphosphanyl-N,N-dimethyl-aniline; dichloropalladium (2 mg, 0.002825 mmol) and K2CO3 (28 mg, 0.2026 mmol) in toluene (1000 μL) and water (120 μL) were heated to 100° C. overnight. The reaction was diluted with DCM, washed with water followed by 1M NaOH, dried (MgSO4) and concentrated in vacuo. The material was used crude in the next step (quantitative yield assumed).
