To a suspension of Xphos (0.695 g), 3-bromo-1H-pyrrolo[3,2-b]pyridine (3.59 g), 2-[4-(methoxymethoxy)phenyl]-4,4,5,5-tetramethyl-1,3,2-dioxaborolane (4.81 g) and Cs2CO3 (11.86 g) in DME (50 mL) and water (10 mL) was added Pd2(dba)3 (0.334 g). The mixture was refluxed overnight under Ar atmosphere. The mixture was added to 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 (0.650 g).
