Reaction Steps

A mixture of 1-(4-bromo-2-chlorophenyl)-8-chloro-5-(1-ethylpropyl)-2,3-dihydro-1H-imidazo[1,2-a]benzimidazole (56.5 mg, 0.125 mmol), xantphos (10.8 mg, 0.0188 mmol), tris(dibenzylideneacetone)dipalladium (5.7 mg, 0.00625 mmol), cesium carbonate (61.1 mg, 0.188 mmol), acetamide (14.8 mg, 0.250 mmol) and tetrahydrofuran (0.5 mL) was stirred at 70° C. for 5 hrs. After cooling, the mixture was diluted with ethyl acetate and the precipitate was removed by filtration and the filtrate was concentrated in vacuo to give the title compound as an amorphous (3.8 mg, 0.0088 mmol, 7%).
