Reaction Steps

To the solution of 4-bromo-6-aminobenzimidazole (0.85 g, 6.0 mmol) in sealed tube with 10 ml of DMF was added tetramethyltin (1.7 ml, 12 mmol) and bis(triphenylphosphine)palladium(II) chloride (0.20 g). The resulting reaction mixture was stirred for 12 h at 140° C. and concentrated in vacuo, yielding oily residue which was subjected to column chromatography (5% MeOH/CHCl3)to produce 0.28 g (45%) of the desired product.
