Participants

Reaction Steps

To a round bottomed flask was added N-(4-(3-bromopyridin-2-yloxy)phenyl)-1H-benzo[d]imidazol-2-amine (0.5674 g, 1.488 mmol), 2-(3,6-dihydro-2H-pyran-4-yl)-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (0.938 g, 4.47 mmol), PdCl2(PPhtBu2)2 (0.093 g, 0.149 mmol), and potassium acetate (0.698 mL, 11.16 mmol) in ACN (3.72 mL) and water (1.240 mL) at 100° C. to stir. Upon completion, reaction allowed to cool to room temperature. Solvent was evaporated. The crude product was purified by reverse-phase preparative HPLC using a Phenomenex Synergi column, 4 micron, MAX-RP, 80 Å, 150×30 MM, 0.1% TFA in ACN/H2O, gradient 25% to 90% over 20 min to provide N-(4-(3-(3,6-dihydro-2H-pyran-4-yl)pyridin-2-yloxy)phenyl)-1H-benzo[d]imidazol-2-amine. MS (ESI, pos. ion) m/z: 385.0 (M+1).
